New robotic hand made from coffee filled ballon

[toxoph]

Sorry if this was mentioned elsewhere here (I did a search and didnt see it), I'm sure some of you have seen this already. I saw this on TV the other day and thought it was really ingenious. I dont know how hard it would be to make this and adapt it to a homemade LEGO bot. Anyways, see what you think
