We've made lots of papier mache transportation in the past but we never went mechanical and made actual spinning wheels for them. So when my boys played with them, they just sorta dragged the papier mache cars around. Lol!
And so, scraps that would've made it into the trash --and possibly, into the ocean-- became an extension to papier mache magic. :P We got a Woody Pop box with a plastic window, Pringles lids, a milk can locking strip, and some juice and choco milk tetra box straws.
And THAT... is how we roll.
