String Science Game

Guitars have strings and make pretty music when played. Violins and banjos also have strings and also make music.

So it makes sense that strings can produce music.

In this experiment you won't have a musical instrument. But you'll hear sounds coming from the strings that will amaze you!

Need: 2 pieces of string about 10 inches long, 2 paper clips, one small can and one paper cup

Take the can and fill it 1/2 full with water.

Using a pin, get an adult to make a hole in the bottom of the cup.

Get a piece of string and tie one paper clip to one end of it.

Take the other piece of string and pull one end through the hole in the bottom. Tie the other paper clip to the top of this string.

Take the first string not in the cup by the paper clip and hold it between your fingers.

Dip your fingers in the water in the can and get them wet. Starting at the top of the string, squeeze it, then move your fingers up and down the string.

You should hear a sound!

Now take the string in the cup and pull the string the rest of the way through.

Hold the cup in your hand and dip your fingers in the water again.

Once again, squeeze the string and move your fingers down it and back up.

You should hear a different sound!
