This is an easy one to do and a MUST for all boys (useful for girls too!). Buy a cheap styrofoam cooler, borrow a handful of tees from a golfer, and grab the hammer from the toy tool bin in your sons room.
When you present it, make sure that you talk about holding the tee with 2 fingers while hammering with the other hand. Josh was tempted to push it through a bit so he did not have to hold it but after a few gentle reminders he got the hang of it!
