Walk on Water- 7 ft. Water Ball

Better get one before the manufacturer gets sued to oblivion.

This is either the coolest or most dangerous thing to be featured here so far. Designed for walking on water, this giant inflatable ball measures 7 feet in diameter. Apparently you just step in, zipper up and inflate it around you.

What could possible go wrong? Oh yeah, deflation and inevitable death by drowning. 
Here's a video of the water ball in action
