These boats were made with homemade play dough. The bird bath served as our puddle and the wend blew the boats around. I ate a half of an avocado out of it’s shell with a spoon. When I was finished eating it, the shell made me think of a little toy sailboat. Some clay, purchased or homemade**, (or maybe just some chewed bubblegum) could be pressed into the bottom of the shell to weight it so it wouldn’t tip over
