Long ago I found a broken Magic 8 Ball. After getting die on my hands I realized the "magic" could be turned into a die. This is an after-the-fact set of my procedures of the process.
Step 1: Paint the Die
Put the die on a pin or paper clip and paint it.
Step 2: Lettering
Use a razor knife to carefully clean off the lettering.
Step 3: Roll It
Ask it a question and give it a roll. I keep mine in the kitchen and consult it often.
