Cup of Sounds
Did you know you can create unique sounds by using some ingredients from around the
house.
Ingredients
Instructions
STEP 1: Using a knife, create a hole in the bottom of the plastic cup.
STEP 2: Cut about 2 feet of string and thread the string through the hole in the plasticcup.
STEP 3: Tie a knot in the string big enough so the string will not pull out of the hole in
the plastic cup.
STEP 4: Wet the sponge, grab the string close to the plastic cup with the sponge, and
then pull downward.
Explanation
You created vibrations in the string by moving the wet sponge along the string. These
vibrations produced sound which was amplified as it passed through the plastic cup.
