He found another fun game to play with his inEXPENSIVE toy. If you push a bunch off the counter at once and they drop into a laundry basket, it sounds a bit like a machine gun. And, if you put some into a little metal bucket and drop it, the sound is like a BoMB!
Unrelated, but still very fun... we made these candy canes. They are quite addicting, fulfilling, fast to make and I'm very sure you have all supplies on hand.
