So the Summer Sylvari Cosplay adventure for Luna, Elah, Anther, and I wrapped up with the end of Otakon this weekend. We had an absolute blast at both AnimeNext and Otakon 2014 this summer, meeting a lot of Guild Wars 2 fans from multiple servers and areas and getting tons of pictures, excited squeeing, and plenty of stares. We’ve learned a lot of craftwork from this summer, and though it’s seemingly impossible to not sweat profusely in those suits no matter where we were, it was all so totally worth it. :)

Ran into a group of swampbenders and the Commando from Guild Wars 1 who we’ve been seeing since last year, which was nice. Never ran into the one other GW2 cosplayer at Otakon that we heard about, unfortunately, but it happens.

It’s been great cosplaying such a beautiful race from such a wonderful game, and I appreciate everything we’ve done for each other, both in and out of game. Many thanks to ANET and the Guild Wars 2 team for the cosplay opportunity, it’s been a wild ride.

Of course this little house was Malfoy’s, now that Harry thought about it. All the precise neat little right angles, like Malfoy used to chop Flobberworms. Definitely Malfoy’s house.

Harry reached the front gate, and with a final glance back down the street, opened the front gate to step through.

Of course this was—

The ground disappeared beneath him and Harry could do little but sigh as he fell through the magical barrier and ended up sprawled on the cool marble floor of a posh grand entry hall. A painting of a white peacock hung on one wall.

Of course this was Malfoy’s house.

Aerogel is an extremely light porous material formed when the liquid inside a gel is replaced with gas. When combined with water, aerogel powders can have some wild superhydrophobic effects. Here water condensed on a liquid nitrogen cooler has dripped onto a floor scattered with aerogel powder from the nitrogen’s shipping container. The result is that the water gets partially coated in aerogel powder and takes on some neat properties. Its contact angle with the surface increases - in other words, it beads up - which is typical of superhydrophobicity. When disturbed, the water breaks easily into droplets which do not immediately recombine upon contact. With sufficient distortion, they can rejoin. You can see some other neat examples of aerogel-coated water behaviors in this second video as well. (Video credit: ophilcial; submitted by Jason I.)
