Invisible bike helmet

I just saw a brief movie (3:37) about an invisible bike helmet on Treehugger.com, and I had to share:

You'll want to watch it with English subtitles.  Watch it first, then read my comments below.



While I was watching the first time, I didn't understand why the two creators kept on biking around with nothing on their heads!  This isn't Hogwarts; there can't actually be an invisible helmet.

At the end of the movie, I wondered lots:  What do you do after it inflates?  How easy is it to deflate and pack up again?  Does it always inflate when it's supposed to?

What do you think of the invisible helmet?
