Experiment: Water Xylophone (Camp Edition)
Make some music with this super simple DIY water xylophone sound science experiment. All you need are a few matching glasses, a spoon and water (food coloring is optional but it adds to the fun).
- 5 or more matching glasses or glass jars
- measuring cup or pitcher
- food coloring (optional)
- chopsticks or metal spoon
Step 1: Line your glasses up in a row.
Step 2: Fill your measuring cup or pitcher with water.
Step 4: Add food coloring to the water until the desired shade is reached.
Step 5: Fill the glasses with different amounts of water in each glass.
Step 6: Grab a spoon and start tapping the glasses gently to make some sweet, sweet music.
Step 7: Does tapping the sides of the glasses make a different noise than tapping the top?
Step 8: Try using different tools for tapping. Can you tell the difference between a metal spoon and a wood or plastic chopstick?
What in the WOW is happening? Tapping the spoon on the glasses creates a vibration, which sends a sound wave through the water in the glass which makes the sound you hear. Wowzer!
