Materials:

Silicone caulk
 
Tools:

As with all projects, read all of the instructions first, before proceeding to make your own.

Step 1: Prepare the head

Take the head off the Pez dispenser. To do this, just pry it back until snaps off.

Tape the head down to your work surface. We used a paper plate (and also a tray) so we could move the project to let it dry. Be sure to tape off the back of the head, to form a wall.

Tip: You could set the head in a lump of modeling clay, but be sure to still tape off the back of the head.

Step 2: Create a rig

The plastic cap will need to be held in place while the caulk sets.

You can make a simple rig by poking a pencil all the way through a soda can, near the top. Add water to the can, to make it heavier and stable.

This will give you something to suspend the cap from.

Step 3: Glue the cap in place

Fill the head with silicone caulk.

Push the plastic cap onto the end of a pencil, and push the cap into the latex caulk, just so that it is completely covered. Try not to let the caulk overflow, and cover the pencil.

Tape the pencil to the rig, to hold it in place, and allow the caulk to set/dry.

Step 4: Put it on your bike!

After the caulk sets (could be a couple days), just pop the head/cap off the pencil, an replace your old stem cap with your favorite character!

I've built quite a few valve cap covers in my day but never figured out how to do Pez heads. Your mounting device is awesome and now I can continue my work. Thank you for sharing.

I like this idea.

Thanks, just make sure you use a caulk or glue that sets quickly. Trust me, latex caulk does not!

Great idea! Seems to me you could pretty much do the same with anything. I'm thinking of making valve stem caps from dice using the same method.

Yes, I've done dice before. They are pretty easy, because all you need to do is drill the right size hole, and glue the caps in place.
