This project was inspired by my aunt and uncle. I made magnetic ping pong ball eyes in order to make instant faces in the interesting metal objects around me. It's a very simple (and weird) project, but it can have some very funny results.
Step 2: Drill the holes
By just spinning the drill bit by hand you can make a hole in the ping pong ball. I started with 1/16" bit and worked my way up to 1/4", this produced the roundest holes.
Step 3: Gluing the magnets in place
Make sure that you are inserting the magnets with opposite polarity facing out. You want the eyeballs to be attracted to each other when you're done.
Attach each magnet to a nail. Place the nail in a clamp. Insert the magnet into the ping pong ball so that it just pokes out of the ball when resting on your work surface. Now run a small bead of glue where the magnet meets the ping pong ball. Wipe the bead down with your finger and let it fully dry.
Double check that the ping pong balls will attach to each other.
Step 4: Dip the ping pong balls into liquid rubber
This step could be skipped if you started with solid white ping pong balls, but I feel the rubber makes the eyes more rigid. With the magnet still attached to the nail (or you could use one of the drill bits like I did), dip the ball into the white Plasti Dip. One coat should do. Allow to fully dry.
White paint could be used instead of the rubber.
