How to Make a Smart Kid’s Phone

What You’ll Need:
Two cups – plastic or paper (preferably) A long string – plastic or thread A safety pin or ball point pen Scotch Tape
Step 1: With your pen or safety pin, punch a small hole into the bottom of each cup.
Step 2: Slip one end of the string through the hole of your first cup, then tie a knot at the end so that the knot sits at the base of the inside of the cup. Tape the knot to the inside of the bottom of the cup. This will create more surface area for the vibrations and enhance sounds coming through.
Step 3: Repeat Step 2 with the second cup, using the other end of the string.
Step 4: Once your cups are connected, two people will be able to communicate through them as long as the sting is kept taut. Try standing in different rooms with the cups and talking to each other! It really does work!
