This tricky thing

[jasontassi]

Grab both of your hands behind your back. And without letting go get them in the front of you. If you can explain how you do it.

You don't specify if you grab them at the base of your back. It's easy to do if you put your hands up and over your head, and hold them together at the top of your back, no? Just lift them back over. Otherwise it depends how long your arms are, or how short your body. Some can put their hands under their bum from a seated position and feed their legs through. I think this may take good flexibility though.

These wouldn't be hands of cards, would they ?

[wallyboots]

AHHH! sneaky. I knew my spidey sense was tingling with this one.

No It is as jasontassi has said and is not cards. You have it right wallyboots - hands behind back, slip over bottom and then step through. I can get my hands over my bottom but an not supple enough to get my legs through the gap - can be done though - seen it done many a time.
