# 30 feet deep

How far can I toss a kobold?

Context: It’s my first legit game of D&D, And i decided i wanted to play a Lizard folk barbarian, and one of the other members was a Kobold monk.

GM: “You see a moat that measures around 30 feet and 10 feet deep.”

Dwarf paladin: Can we swim across it?

GM: The guards will see you if you don’t sneak.

Kobold monk: Well I have proficiency in sneak….

Me: How far can I toss a kobold?

Kobold & others :Excuse me? What? Etc.

GM : Whats you’re strength and your height?

Me: 15 and i’m 7'1…

Gm: 50 feet, athletics check on advantage.

Kobold: Wont the guards still see it?

Gm: Good point, both of you roll stealth after he rolls to throw you.

Me: *Rolls nat 20 for athletics and then a  nat 20 on stealth, .*

Kobold: *Rolls a 5 on his stealth.*

GM: So, the lizardman picks the kobold up by both of his arms and starts spinning him around before letting him go, the guards couldn’t see him as he was perfectly hidden by the shade from mountains in the distance, but they do notice a SCREAMING tiny lizard sailing through the air over the moat. tiny lizard monk, give me an acrobatics roll.

Kobold *rolls 1*

Gm: And the kobalb does not stick the landing….in fact he thought the wall would cushion him….the kobold is unconciouss and will wake up in the dungeon after he wakes up.

Kobold: Why would you do this.

Me: I wanted to see how far i could throw you… It’s your fault that you couldn’t be thrown right.

Theoretically, if humans were to keep blue whales in captivity, how large of a tank would they need to be kept in?

I have no idea. Like, it’s so off the radar - even theoretically - that it’s really hard to give you an answer. But, okay, I have engineers in my family I can pester, so let’s think this through.

The things we’d have to consider for what a blue whale would need would be like: how much physical movement does such a huge animal need a day; what sorts of ways does a whale move (do they corner well? if not, better not have a tank with anything resembling corners); how deep do they need to dive, and for how long. Blue whales frequently dive to 330 feet below the surface to feed - yikes, there’s no way we can replicate that in a tank - but we could at least try to give them maybe 100 feet in our hypothetical tank. When migrating, blue whales sustain speeds between 3-6 miles per hour and top out around 30, so they’d definitely need a lot of room to move.

The biggest fish we keep in captivity right now is a whale shark, the largest known specimen of which in the wild was about 40 feet long. The Ocean Voyager tank at the Georgia Aquarium is 6.3 million gallons of water and currently houses four whale sharks (and in my personal opinion still isn’t big enough for that number of animals). Blue whales grow to around 80 feet long. So you’d be looking at designing a tank for an animal that’s twice as long as a single whale shark … but is something like eight times heavier. (The heaviest blue whale known was 170 tonnes, whale sharks tend to be around 20 tonnes as adults). The Ocean Voyager tank is 284 feet long, 126 feet wide and 30 feet deep, so to scale that up for a much more massive animal? That’s going to be a damn big tank.

As it stands, GA’s whale shark tank is one of the biggest tanks in existence in the world, and for anything to potentially be anywhere near appropriate for a blue whale, my guess is we’d start pushing the limits of what is physically possible to build. Water is heavy, and containing it requires the walls and support structure for the tank to be able to withstand a lot of pressure.  Basically, the pressure of the water in a tank is distributed across the bottom and the sides of t a tank. When we start talking about larger or deeper tanks, we run into issues with not the bottom of the tank being able to hold all that weight, but with the strength of the sides. Surfaces are generally better able to resist compression than tension, and the sides of a tank are basically being stretched by the pressure of the water. The bottom of the tank is supported by the ground or whatever structure has been built underneath it, but the integrity of the sides relies only on their shear strength, resistance to crack propagation, and resistance to corrosion. As a result, the sides have to be really, really beefy - even for just the tanks that currently exist. The acrylic viewing windows for the GA tank - which is only 30 ft deep - are two feet thick due to the sheer pressure exerted by the water within it.

If we’re talking about a tank that has a large enough footprint for an 80-foot whale to be able to turn around comfortably and deep enough for a blue whale to dive at least somewhat… there’s probably not enough concrete in the world to build a tank strong enough to contain that much water. It would be much easier to shore the walls of a tank up with something like dirt -  although that would make viewing windows hard, because you’d probably be talking something like ten feet of acrylic to make sure all the edges of the tank had the same amount of structural support.

I think, in short, that your hypothetical blue whale tank would probably end up being a very deep, very salty artificial lake.

(Also, if we’re talking about an actual tank that has to be maintained, it would be ridiculous. If we’re sticking with a hypothetical 100 foot deep tank, that means the pressure at the bottom is going to be four times higher than standing on land (every 33 feet you go underwater, you’re experiencing another atmosphere of pressure). Someone would have to go in there to clean and maintain the tank fairly frequently, which is not a simple task. It’s dangerous and time-consuming to dive that deep because you have to stop on the way up to let dissolved gas leave your body - you’d spend twice as much time waiting on decompression stops as you actually would working on the bottom. Very few non-professional divers frequently ever go down that deep, and it’s absolutely not something that would be safe for a person to do on a frequent basis).

Tungkwan, China

One of the most radical solutions in the field of shelter is represented by the underground towns and villages in the Chinese loess belts. Loess is silt, transported and deposited by the wind. Because of its great softness and high porosity, it can be easily carved. In places, roads have been cut as much as 40 feet deep into the original level by the action of wheels. In the provinces of Honnan, Shansi, Shensi, and Kansu about ten million people live in dwellings hollowed out from loess.

The dark squares in the flat landscape are pits an eighth of an acre in area, or about the size of a tennis court. Their vertical sides are 25 to 30 feet high. L-shaped staircases lead to the apartments below who rooms are about 30 feet deep and 15 feet wide, and measure about 15 feet to the top of the vaulted ceiling. They are lighted and aired by openings that give onto the courtyard.

From the top one can only see small trees placed carefully above each staircase that leads downward. The tree acts as the official sign of the house, so you don’t describe your house to visitors or give a house number but tell them about your tree.

Sinkhole opens up at National Corvette Museum, swallows cars

A massive sinkhole that opened up under a Kentucky museum Wednesday morning swallowed several vintage and rare Corvettes.

The National Corvette Museum said the Bowling Green Fire Department estimates the sinkhole to be around 25-30 feet deep and 40 feet wide.

Six of the cars in the sinkhole are owned by the museum; two others are owned by General Motors.

“It is with heavy hearts that we report that eight Corvettes were affected by this incident,” the museum said in a press release.

The museum is closed for the day.

An estimate of the cost of the damage done to vehicles and the museum has not yet been determined.

# Moray -Peru

Unlike a number of the elaborate metropolis’ and statuary left behind by the Incan people the rings at Moray are relatively simple but may have actually been an ingenious series of test beds. Descending in grass-covered, terraced rings, the rings of rings vary in size with the largest ending in a depth of 30 meters (98 feet) deep and 220 meters (722 feet) wide. Studies have shown that many of the terraces contain soil that must have been imported from other parts of the region. The temperature at the top of the pits varies from that at the bottom of the ringed pits by as much as 15 degrees Celsius , creating a series of micro-climates that not coincidentally match many of the varied climate conditions among the Incan empire. It is now believed that the rings were used as a test bed to see what crops could grow where. This proto-America’s-Test-Kitchen is yet another example of the Incan ingenuity that makes them one of the most remarkable of declined societies in the planet’s history.

Today in History, July 30th, 1864, — The Battle of the Crater

In 1864, with the Union Army under the command of Gen.  Ulysses S. Grant, the Union went on the offensive in Northern Virginia in a attempt to capture the Confederate capitol of Richmond.  Despite fighting Gen. Robert E. Lee’s army to a standstill, Grant continued to press Lee’s left flank, keeping Lee on the defensive and pushing closer and closer to Richmond.  Then in early June the offensive came to a screeching halt when the Union Army attempted to take the City of Petersburg, a mere 23 miles away from Richmond.  The Confederates had turned Petersburg into a heavily armed fortress, with over ten miles of trenches complete with bunkers and anti infantry obstacles.  Despite a number of heavy assaults by Union forces, the Confederates were able to hold their ground.  Unable to decisively take Petersburg, Union forces dug their own trenches and built their own fortifications.  Foreshadowing the bloody combat tactics of World War I, both sides settled into trench warfare and bloody attrition.

In mid June the commander of the 48th Pennsylvania infantry offered a novel solution to the stalemate.  Lt. Col. Henry Pleasants was a mining engineer before he joined the army, and many of his men, recruited from Schuylkill County, PA were also coal miners.  Pleasant’s idea was to dig a tunnel under the Confederate fortifications, load it with explosives, then blast the Confederates straight to Hell in small pieces.  The resulting break in Confederate lines would leave their defenses vulnerable to a Union assault, thus ending the siege.

Digging of the tunnel began in late June and was completed by late July.  Once the tunnelers reached the Confederate lines, they dug another tunnel that ran parallel to the Confederate trenches above, thus making a “T” shape.  The main approach shaft was 511 feet long and located 50 feet below the ground.  Once the tunnel was completed, it was loaded with 320 kegs (8,000 lbs) of gunpowder.  On July 30th, 1864 the fuse was lit at 3:45 AM.  An hour later a massive explosion occurred amidst the Confederate lines.  The resulting explosion instantly obliterated 278 Confederate defenders, and left thousands of other in state of shock from the massive blast.  In the middle of the Confederate trenches was a large blast crater around 170 feet long and 30 feet deep.

To conduct the assault Union Gen. Ambrose Burnside chose the United States Colored Division and the US 1st Division.  Burnside trained his Colored Division for weeks in preparation for the battle, choosing them to be at the head of the assault.  The US Colored Division had by then gained a reputation as experienced and courageous veteran soldiers who could be counted upon to achieve the most daring and dangerous missions.  However, at the last minute, Gen. George Meade, Burnside’s boss, ordered the US 1st Division to the front, a unit with little experience and training.  Meade had little confidence in the plan, and didn’t want to waste the US Colored Division in a failed assault.

The plan was that when the two units approached the crater, one battalion was to go around the crater to the left, while the other was to go right.  When the inexperienced 1st Division approached the crater, they quickly occupied it, believing it to be the ideal rifle pit.  Meanwhile the men of the US Colored Division followed their orders and went around the massive pit.  The blame for the failed plan rested on the shoulders of the 1st Division’s commander, Brig. Gen. James H. Ledlie, who failed to brief his men on the assault, and spent much of the battle well behind the lines and drunk in his bunker.

After an hour the stunned Confederates rallied their forces and organized a counterattack against the Union assault.  Confederate troops surrounded the pit, which by then was a confused and panicked mass of men crowded shoulder to shoulder.  In what Confederate Brig. Gen. William Mahone would term “a turkey shoot”, the Confederates rained the pit with musket fire, grenades, artillery, and mortars.  The helpless soldiers trapped in the crowded pit could little defend themselves against the hail of Confederate lead.  If the suffering of the men trapped in the pit was bad, the fate of the Colored Division was even worse.  Without the support of the 1st Division, the Colored Division was quickly outnumbered and surrounded.  Many of the men were able to break free and retreat, however a number of regiments were forced to surrender.   Many Confederate officers, angered by the thought of former slaves fighting for the Union, gave orders to execute black soldiers and officers who surrendered.  Most of the black soldiers who surrendered at the Battle of the Crater were executed by bayonet on the spot.

Eventually a Union relief force was able to free the men trapped in the crater.  By the time battle had ended, Union forces suffered 3,798 casualties (504 killed 1,881 wounded, 1,413 missing or captured).  Confederate losses were also high, with a total of 1,491 casualties (361 killed,727 wounded, 403 missing or captured).  The Battle of the Crater turned out to be the Union most embarrassing defeat; an intricate and complex plan that was to bring about a surefire victory, failed because of bad leadership and a drunkard.  After the battle, Gen. Ambrose Burnside would receive most of the blame for the defeat, and was censured and relieved of his command and spent the rest of the war in a desk job.  He would later be cleared of fault by a war committee, who instead blamed Gen. Meade for the last minute substitution of the US Colored Division with the 1st Division.  Gen. Ledlie “The Drunkard” was charged with dereliction of duty and his commission was revoked.

The Siege of Petersburg would last 9 months total, finally coming to an end on March 25th, 1865.  The fall of Petersburg left Richmond vulnerable, leading to its capture of Richmond on April 2nd.  Robert E. Lee then surrendered a week later.

Today I went to Jacob’s Well in Wimberly, TX.

It’s recently gotten very famous on various social media (mainly tumblr and twitter) but what most people don’t know, is how this natural phenomenon got it’s name.

Many Wimberly residents (and some people in the Hays county area) are very familiar with the urban myth of Jacob. Jacob is actually a local “monster” who has been said to pull people into the bottom of the well. This well is approximately 30 feet deep, and has an intricate cave system in it. Not many people have successfully scuba dived in this underwater cave system. Many have supposedly gotten stuck in part of the cave, but for many years residents have blamed it on the creature, Jacob.

Some people believe that Jacob only resides in the well, but others may tell you that he runs around in the forest also. Every account of a Jacob sighting has described him as a “gremlin-like creature, too fast to get a good look.” That’s why only brave souls (or people who just don’t know) jump in. There is a sign at the entrance of the area, but I didn’t get a picture, so I’ve also included a link to a Wimberly news article over the latest sighting:

So, next time you go to Wimberly,Texas look out for the gremlin, Jacob! Or go to a local shop and ask a resident all about it!!! It’s really some interesting stuff!!!

Can you tell us a story about the first time you used lsd? Can you do it like detailed? I'm planning on doing it for the first time tomorrow and yeah, I just want to hear stories about it! Thank you in advance!

Oh my this is a bit of a long story.
Sorry if this is too long to keep your attention.
The first time I did LSD was about 8 years ago. I was actually really sick with a cold. I was really congested and I knew stimulants made for fantastic decongestants. Not wanting to go to a doctor I decided to get a few hits of ecstasy, because it was one of my favorite substances at the time. By happenstance I found someone I worked with who had three tabs, a green clover, a white Mercedes, and a double stack blue superman. My workday started at midnight and ended at 8am. So I got the X from my coworker around 1am, took the green clover, an hour later took the white Mercedes, and two hours after that took the blue superman. Needless to say I was rolling REALLY hard. At around 5:30am another coworker told me a friend if hers had some acid. I was so excited about it because I had been trying to get some for two years. We decided to leave work immediately to go get the acid.

It should also be noted that the day before this experience I was incredibly sick, and by the time the trip was over my illness was completely gone.

Jellico, Tennessee, is divided by the State line between Tennessee and Kentucky; giving the town its sister city of Jellico, Kentucky.   On the Kentucky side stand the ruins of these two Lodges.    Yep, we said “Lodges” as in “plural”.

Masonic Lodges have a way of naturally bringing questions to mind; and the remains of the Boston Lodge #593 certainly live up to that tradition.   First, there’s the question of why it shared one of its brick sidewalls with another lodge, the Hillside Lodge #51.   Both were obviously built at the same time and using the same design.  I’ve never before seen two different numbered lodges right next door to each other.  Plus, the history of the lodges seems to have been virtually swallowed up by the passage of time.   I couldn’t imagine not being able to track the history of a Masonic lodge in a town; especially when that history would have included there being two conjoined lodges in the same building.

I suppose the historic Jellico train explosion on September 21, 1906, could have had something to do with the demise of the building.   In that disaster, most of the town was destroyed when a  train cargo car loaded with 11 tons of dynamite exploded in the Jellico downtown rail yard, which was quite close to these lodges.   The explosion left 8 to 12 (depending on whose report you believe) dead, 200 more injured, and 500 homeless.   Reportedly, there wasn’t an unbroken pane of glass remaining in any building within a mile of the rail yard; nor was there a chimney left standing; and the explosion made a crater that was 30 feet deep and 100 feet in diameter.     Interestingly, these lodge buildings are surrounded by the shattered remains of several other buildings.

We’ll certainly be going back for a closer look at the area, sooner or later.   There was a very interesting feature to the buildings that needs to be explored, but to do so will require some equipment we didn’t have along with us.

SEPTEMBER 6, 2015  UPDATE:

Today, I found the answer as to why there were two lodges built right beside each other in Jellico.    The first half of this riddle’s solution is that I was mistaken in believing that these were both MASONIC lodges.   They were not.

Boston Lodge #593 was definitely a Masonic Lodge; but Hillside Lodge #51 was a lodge of another organization known as the “Knights of Pythias”.    This explains the letters “KP” in the lodge’s name on the front of the building.    While the Knights of Pythias are commonly believed by many to be a part of Masonry, that is not correct.   They are entirely separate organizations.

So, the mystery of why there were two Masonic Lodges right beside each other is finally solved.    There weren’t ever two Masonic Lodges side by side in Jellico in the first place.
