How to Make Sounds With Glass Cups

A simple glass cup of water is the first step to creating musical fun for children and adults.

Making music with water glasses is easy and fun for children of all ages. You'll just need a few glass cups, water and a wooden stick or utensil to get started. As you tap each water glass gently, the sound travels through the water to produce a slightly different sound for each cup. Combine the gentle chimes of the tapping with a shrill singsong sound produced with your finger on the glass, and you are set to create music, whether you choose to play solo or hang with a crowd.

Things You'll Need

• One or more glass cups
• Food coloring (optional)
• Wooden stick or metal utensil

Instructions

1. 

   Color the water in your glass cups to add a touch of fun to this project.

   Fill your cups with water. Vary the water levels between the cups. Add a few drops of food coloring to each cup for a touch of whimsy.

2. Gently tap the wooden stick or metal utensil on the side of the glass cup. Each glass will make a sound of a different pitch based on the water level. Arrange the glass cups according to your musical preference.

3. 

   Use your index finger as a part of the instrument.

   Dip your finger in the cup of water.

4. Run your wet finger, gently and continuously, along the rim of a glass cup to make a shrill singsong sound.

Tips & Warnings

• Try using crystal goblets or wine glasses for a clearer, crisper sound.

• Tap the glass very gently to prevent cracking or breaking.
