Part 1: Build the switch

Now it’s time to put the switch together. Remember to be careful when working with the tin can lids. They’re sharp!

  1. The two tin can lids will be the two sides of the switch.
  2. Use a magic marker to trace the shape of one tin can onto the sponge.
  3. Draw a line to divide the circle you have drawn in half.
  4. Cut a half circle out of the sponge.
  5. Glue the sponge to both tin can lids so that it looks like the picture.
