2. Build a simple circuit using copper tape. Leave one gap for the LED and a second one for the switch. Mark the negative and positive ends and put the LED in its place.

Clip the battery into its place.

4. Apply glue to the dark side of the big magnet and stick the strip at the back of the paper, where the second gap is. This will be the base the switch will cling to.

5. Cover one half of the smaller magnet with copper tape. When you put the magnet on the gap, it will bridge the gap between the two ends of copper tape on the paper, and complete the circuit.

6. Now test it out! Your LED should light up. If it doesn’t, smooth out the copper tape on the magnetic strip with your hands and try again.

7. If you want to take it a step further, you can write on and off nest to the switch. Write ON next to the magnet when the light is on.
