Creating A Homemade Circuit
When I was about 7 or 8 years old I had a collection of circuit kits filled with propellers, light bulbs, and all sorts of circuitry stuff, but little did I know that I could have┬ádone the same stuff using at home items. Recently I attended WPI’s (Worcester Polytechnic Institute) “Touch Tomorrow” science festival where a couple of friends and I were able to make multiple circuits (mine shown below).

Supplies Shown Above:
Batteries (x2)-@ Bottom
Aluminum Foil- Shiny Stuff to the Right
Green Wire-Next to the Aluminum
Electric Tape-Every Black Object
Speaker-The Black Doughnut Shaped Object
Scissors- To Cut ­čśŤ
Piece of Thick Paper (Cut a Square From a Folder)

Supplies You’ll Need:
Batteries (x2)
Aluminum Foil
Electric Tape
Scissors
Speaker, Motor, etc. (Your Choice (As Long as it has a one Black and one Red)-I’ll be using a motor from my hoverboard.
Piece of Thick Paper (Cut a Square From a Folder)

Steps:
1) Tape two batteries together very tightly (the knob touching the flat end)
2) Tape the battery bar to the paper
3) Take a small strip of aluminum and crumple it up, length wise, so that you have an aluminum wire
4) Then connect one wire of the motor to the battery
5) Connect the aluminum wire to the battery and tape the other end of the wire to the paper, but do not cover the end.
6) Repeat step 5 for the other wire so that the bare area at the end of the wire is overlapping the aluminum.
You have now created a switch to turn the motor on and off by connecting the aluminum and wire with a push.
*Note if the motor isn’t working you may need to hold both ends of the battery bar so that the connection works
