Ok, so here is the story... My boy busted his arm on the playground playing cops and robbers. He got his arm set and about a week later, got a beautiful green and black cast. As we were driving him home from school a couple days later, we had a great idea. We decided to 'accessorize' his new arm. We drove to Walmart to pick up supplies...

Step 1: Supplies...

At Walmart we bought a Lego set that had some flat pieces in it. My son has Legos, but he did not want to use any of the ones he has, since they are all Star Wars models. We also bought some waterproof epoxy putty (look for it in the automotive or the home improvement sections of the store).

We also rounded up a few accessories... A voice recorder/changer, a compass, a flashlight, a USB drive and a small box.

Step 2: How To...

Following the instructions on the putty, we mixed and kneaded the putty, and then putty-glued a large flat Lego directly on the cast. We also glued matching Lego pieces onto his accessories! Interestingly, the epoxy putty gets hot as the chemicals react and attach the Legos to the accessories and the cast.

Step 3: Final Outcome...

We let the epoxy set for a couple of hours and then tried out the accessorized cast. The Legos worked perfectly! He could not wait to take his accessories to school!

We showed his arm to mom and she said, "You did what?"

All in all, it was a fun little project and did not affect the cast and made his broken arm more fun. The doctor was able to cut off the cast as usual.
