🎶Musical 💦Water 🌈Glasses (Science 🔬⚗️⚖️ 101 🎥Series 🎇)

Have you tried making a water xylophone? This is a fun and scientific music activity you can do with your child at home. Just fill glasses with different amounts of water and invite your child to make music!


 You will need:

  • identical glasses (we are using four tall crystal glasses) and these test tubes with this stand,
  • food coloring,
  • water,
  • we are using Xylophone sticks, but you can also use wooden sticks or a plastic spoon. 

Arrange glasses in a line and fill them up with water in equal decreasing increments (pouring less and less in the next subsequent glass). We added food coloring to give the water a color-pop. Invite your child to tap each glass and discover the sound each glass makes!


Science mystery💡revealed: sound travels about four to five times faster in water than in air. So, water is affecting the speed at which the sound waves are traveling and vibrating.

This activity is a great way to stimulate senses, exercise your child's science skills, as well as musical abilities. You can even incorporate math by using measuring cups and fractions. Moreover, you can add a sensorial dimension to this activity by offering your child to create secondary colors by mixing primary colors together. Also, invite your child to "compose" a song or play a familiar tune. Finally, explain to your child the "magic" of sound waves. And, most importantly, have fun!
