Fun Item for Kids

This is a giant egg, similar in size to Ryan's other giant eggs. The price was right, so we gave it a shot. There are multiple experiments in the egg that you can do a few times over. Definitely for kids over 5 years old or you will need to help. It can get a little messy. My son liked the bouncy ball the best. Took us a few tries to get it right, but it is pretty easy once you figure out the mold.
