The hypothesis is that sound can be produced by vibrations.

You will fill a stem glass half-way with water, wet your finger with water from the glass, grab on to the base of the glass with the other hand to secure it, and move your wet finger slowly around the rim of the glass.

You will need stemware (all the same size and shape, if possible), water, and food coloring.

After running your finger around the top of the glass, you'll notice that the glass begins to "sing!" You'll also observe that the glass notes changed when the water level changed. This is because the water level affects the ability of the glass to vibrate, which is what produces the sound.

This science project is so interesting and unique because it allows you to explore the science behind sound production in a fun and creative way.

Experiment variations to consider include adding food coloring to the water and experimenting with different sizes and shapes of glasses.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
