Saw this idea in Family Fun magazine (which is my go-to magazine for fun projects to do with the kids), and had to try it!
You will need:
- 1 cheap, hollow, plastic dinosaur
- 5/8 drill bit
- drill
Depending on the thickness of your toothbrushes, you might be able to use a smaller drill bit. Ours were pretty thick, as I think most kids toothbrushes are. All you do is drill the holes right through the dinosaur! Pretty simple. The kids thought this was super cool. Family Fun had suggested using a craft knife, but I thought this would be easier.
