Graphite Circuit Drawings

We decided to create some Easter circuit drawings. (Well, Rachel wanted to draw a cat for her Easter drawing...) 

The graphite in pencils will work to complete an electric circuit, so we drew our faces very heavily with pencil, leaving a little opening at the top of the head and at the bottom. We attached a light to the bottom of the circuit and a 9 volt battery to the top of the circuit. Rachel made her cat's nose light up, and I made my bunny's bow light up.
