Edible Water Bottles? [VIDEO]

What?  Edible water bottle?  How can this be?  Are we saving the planet?  Could this be hit of this year's Boilermaker?I watched this video and personally, I was quite amazed.  The idea is brilliant, however, you probably have questions just as I do.  How long do these things last?  Can I stock up on them so I'm not making them every day?  Can I keep them in the fridge?  Can I make different flavors?  I'm sure the answers will be coming soon.

It's great that we have a recycling program, but look around, especially now as the snow is melting, at all the plastic water bottles that don't make it to the recycling center.  How great it would be to have a product that is mobile and you consume the whole thing!  I see these things hitting the supermarkets soon.  What do you think?
