Recycled Bowling Pins

I have a nine month old so I buy these Gerber puffs in six packs at Sam's Club. The wrapper sometimes peels off when I open them and when I saw that the bare containers looked like little bowling pins I knew what I had to do. See how they have a perfect little rim that make them look like pins?
Today my baby finished off her tenth container so I pulled them out of the cabinet and we colored the little stripes with colored sharpies.
Then I showed him a couple of Youtube videos of bowling since he had no clue what bowling was. He loved the bowling scene from Grease 2. What's not to love...bowling, singing and dancing??? Then I set up the pins.
And he bowled.
I enjoyed reusing containers I already have and he enjoyed "making" bowling pins and spent a good part of the morning knocking them over with different balls. If he were a litter stronger or used a heavier ball I could easily add sand or rice to give the pins a little weight but, for now, he's just working on his aim.
