Watch the video on how to make a circuit puzzle in the supporting documents folder. In your Olympic Kit, you have all of the materials needed to create one. When you touch the correct pair of letters with the two elecrodes/clamps, a light bulb will come on (because the letters are connected by a piece of conductive foil on the back side of the circuit puzzle. What is the minimum number of pairs of letters you will need to test to guarantee that you figure out the 4 pairs that allow the light to turn on?
