Solar Beads

My kids brought home some solar beads from science camp. I put some on my key ring. It only takes them seconds to go from white to bright colors when you take them out into the sun. Take them under a tree, and they turn white again (a bit slower). Pretty cool! You can buy some, too.

Now they are pretty cool, I bet the grand kids would like some of those.
