I will teach you how to make a simple paper circuit.

Step 1: Supplies

Supplies:
Paper
Graphite pencil
9volt battery
gator clips
L.E.D.

Step 2: The Circuit

now use the graphite pencil and create a maze kike the one shown(make sure the lines are consisted of multipal layers.)

Step 3: The Light

At the end of the circuit(the end is the side without the - and +) then tape the led so that the one of the prongs touches one of the graphite lines, and the other prong the other graphite line.

Step 4: Batter

Now connect one side of the two gator wires to the circuit. Each gator clip should be connected to one of the positive or negative blocks. now take the 9 volt and connect the gator clips that has one side attached to the positive block to the positive side of the batter. Now do the same thing for the other except do for the negative side.
