Where can I get those bubbles that kids are inside that float on water?

Question

Ok, so when I was up at a lake in NY last year, I saw these in side these bubbles, floating on water. Where can I get these, and what are they called? HELP!

P.S. I found this video on a website so you know what they look like.
