Electricity Quiz Board

So basically, the game board was just a complete circuit. It had a two batteries, a lightbulb, and a four of wires. When you touch the correct question to the answer, the electrons flow through the wire which make a complete circuit. The question and answer part was just like an extra wire, it doesn't hurt the circuit when it is included. Even without the question and answer part, just connect the two alligator clips and the circuit would still work.
