Everyone knows that Unicorns make rainbows, but it’s not always easy to find a unicorn on short notice. Instructables user Antzy Carmasaic created an awesome paint roller that can paint vibrant 10-color rainbows, which is a huge timesaver when unicorns are scarce. It’s called the Rainbow Roller and Carmasaic created a handy Instructables tutorial to enable anyone else to assemble their very own rainbow-maker.

“One day while just surfing around on the internet, I came across the nyan cat GIF leaving a trail of rainbow in its wake. That got me thinking about how to do the same in the real world. After a bit of trial and experimentation with different types of sponges and paints, I managed to create the rainbow roller as I had imagined it.”

The more ugly, older, more cantankerous, more ill and poorer I become, the more I try to make amends by making my colours more vibrants, more balanced and beaming.
