Hot air sometimes is a good thing

My son's scout troop held the 1st Annual Raingutter Regatta last night.  Take a balsa wood boat kit. Construct it.  Grab a few gutters from the local hardwater store.  Cap 'em off. Add water. And there you have the makings of a Raingutter Regatta.  Great fun had by all.  Tonight's shot could have shown any number of scouts blowing their boats to victory.  But, I think a better post is created by seeing a couple of adult den leaders propelling their own boats to victory.
