pretzel circuit

Today in class we did a lab about circuits. I was an electron and I got 2 pretzel every time I passed the "battery" or pretzel bag.  When I passed a light bulb I had to put a pretzel in the box. The pretzel in the box represented how the electron gives the light bulb its energy. We had to walk on tape which represents wires. In a series circuit we walked along the wire in a straight box but with a parallel circuit we got to chose which way we wanted to go.
