That cold weather we had last week sure made people do crazy things. Here’s yet another trick from the polar vortex. It’s video of a guy dunking his T-shirt into a bucket of water, and then laying it flat on a snow-covered backyard deck. He lets some time pass, and then picks it up . . . and you can see that it’s frozen. It kind of looks like a cardboard T-shirt. Then he folds it like you would a paper airplane, and sends it flying. I think I know how I’m going to spend my Saturday now.
