FREE: Foldable Unbreakable Flower Vase!

Do these inflate only when water is added to them? I mean they wont be any good with artificial flowers, right, where you don't need any water?

Good question... Here's a video I found about another brand. http://www.youtube.com/watch?v=Zk8gJ9CyeJA

I don't know what's up with that link, but here's a description I found, so I think you're right. Not for fake flowers!
"Vases come in all shapes and sizes and you probably have a collection of them taking up tons of space you would rather use for something else. Flipo has created an excellent alternative with our plastic foldable vases. Currently available in 6 different shapes and colors, our foldable plastic vases offer unique decor solutions as well as minimal storage space. To use them, simply squeeze the flat vase to unfold it, fillit with water and add flowers. That's it! Flipo foldable plastic vases are the perfect solution for that surprise bouquet of flowers or flower arrangement. And because they have such a unique look, they're much more interresting. Our Flipo brand foldable plastic vases actually compliment and coordinate a flower arrangement with existing room decor. Try that with a plain clear glass vase. When you're done with them, simply pour out the water, wipe them and fold them flat in a drawer for reuse later on."
