In 1960, Col. Joe Kittinger rode a helium balloon up to 102k feet to the very edge of space, and then jumped from the open gondola, skydiving back to earth. My five year-old son loves watching the video of this, which is on one of his Planets videos. He loves to pretend he's the guy jumping from the balloon by jumping from the playground equipment onto the sand when I take him to play at the park.
Here's the Youtube equivalent of Col. Kittinger's jump:

How fun would THAT be?
