Making Halloween skulls from recycled plastic milk jugs

One of my all-time favorite Halloween projects is milk jug skulls. Using HDPE plastic jugs you simply heat the material over a skull form (easily found online) and shape and cool it with a sponge and cold water. That's pretty much it.

In the above video from Make: magazine, Caleb Kraft shows how it is done.
