Fun accessory Charlie. I've got a 6 YO gs that would have fun with one of those.
A 6 year old can build this kit. No glue. Very good picture directions. The only difficult part is snapping the pieces out of the mold frame (your job).
For $18.00, I thought this was a great kit.
Put together as a cart, a child can push it around the floor.
A little cotton inside the drum will dampen the noise nicely.
