We asked how many people can juggle. Here is a demonstration of some impressive juggling with three balls by Timo Wopp, maybe a little better than you can do.
We asked how many people can roll their tongue which we meant was rolling it into a tube. Here are a video of a lady who can not only roll her tongue into a tube, but do all sorts of rolling and twisting of her tongue. I don’t think this is something that you can learn to do, just either you can or you can’t. The tongue is one big muscle that can do some pretty neat things.
