Bottle Opener. Lost Foam Metal Casting

I wanted to make some useful bottle opener with unique or at least nice design.

Step 1: Preparing the Mold

As a mold I use big beer can and green sand. I've made bottle opener sample from a plastic foam.

Step 2: Aluminum Is Melted and Ready for Pouring

When aluminum is melted it's time to cast it.

Step 3: Result

I like how it finally looks. It's not just a bottle opener but can be easily used as a keychain.
