I came across a piece of material yesterday. It looks like a thick piece of paper (1/16" thick).
When you add water, it turns into a sponge (about 11/16" thick). The sponge seems pretty tough too.
I'm thinking that a 3 X 5" piece would fit nicely in a small kit and expand when needed to provide a usefull sponge. There are lots of other uses, too.
Is anyone familiar with this material? If so, what information do you have about it? Any comments are appreciated.
Thanks
