I figure some of you might want non-9/11 material to be looking at today. So... would you like to learn how to turn a ball inside-out? Yes, you would. Stop saying silly things like 'no' and 'stop asking me that' and 'you're in violation of the restraining order'.
The easiest way would be to poke a hole in the ball and pull the inside of the ball out through the hole. But it is possible to do it without poking any holes, or making any creases.
You just need an infinitely stretchy ball.
And also you need to be a superhero. Shadowcat of the X-Men, specifically.
