This project shows you how to complete a circuit through two boxes.

Step 1: Step 1: Cut and Glue Cardboard

Gather cardboard from boxes and cut them into these measurements:

4 7" 1/2 by 7" 1/2 of cardboard for box

4 9" by 9" for key box

both widths 3 inches

You will be making two boxes, one for the key and the other for a regular block.

Once you have everything cut up into the correct measurements, glue them together to create a square shape.

Step 2: Step 2: Cut and Glue Diffusion Cloth

Gather Diffusion Cloth and cut it into a 7 1/2" by 7 1/2" and 9" by 9" square. After you finish cutting it, glue it only to the cardboard box with the corresponding measurements.

Step 3: Step 3: Copper Tape

Once your block is made, place copper tape around the perimeter of the box.

Step 4: Step 4: Makey Makey and Scratch

Connect Makey Makey to the computer
Open up Scratch on the computer
Connect a wire to the ground on the Makey Makey
An alligator clip will be connected to your desired key (spacebar)
The other end will be connect to another wire that will be connected to the box (step 6 shows you how it will be connected)

Step 5: Step 5: Scratch Instruction

This step will show you what to program scratch so that a sound will be made when the copper tape is touched.

Click "Events"
Drag "when _____ key pressed" onto the space on the right
The little black arrow pointing down will allow you to change which key you want to press to make an outcome. In this case, it will be space bar.
Next click "Sounds"
Drag "play sound _______" and drop it right under the "when _____ key pressed" you dragged out earlier

Step 6: Step 6: Connecting Program to Block

Once you have the program up with all the wires and your desired action in place, you will now connect the wires to the box.
With your wire, bend the metal so it will be horizontal when you hold it up.
Lift the copper tape
Make a tine hole in the box where the copper tape once was
Insert the bent wire through the hole and place the horizontally.
Put the tape down to where it was before, but this time with the wire underneath it.
