You may have read of heard about this stuff already. It's a spray-on plastic coating that lends a very impressive amount of strength to whatever it's sprayed on.

Superlight Aerogel

Aerogel is an amazing material. You can purchase samples of it online for a reasonable price. In compression, it is about as strong as tightly packed sand. When they say it reacts poorly to moisture they aren't kidding - it will melt as you breathe on it, or leave behind a fingerprint from the moisture in your fingers. I showed the sample I purchased to the kids and within a minute of experimenting there was nothing left.
