Head in a Jar What you’ll need: Bottle, flattened printout of a face, theatrical hair, screwdriver and cork How to make it: Search Google for a “face texture map” for a flattened rendering of a face that would be applied to a 3D model. Scale the drawing and print it out. Roll it up and feed it into the jar. Then crumple paper to stuff into the center of the jar, so the face flattens against the inner surface of the glass. Add fake hair,, using a screwdriver to help arrange it strategically in the jar. Close with a cork and hot glue it shut.
