Transparent Umbrella Bags – Sound Wave Experiments, Pack of 100

These Transparent Umbrella Bags provide a simple, visual way to investigate sound vibrations and the transmission of sound waves in school science classrooms.

By inflating a bag and placing a small quantity of lightweight particles, such as rice grains, inside, students can observe how nearby sounds cause the particles to move. This hands-on activity helps demonstrate the relationship between sound, vibration and movement.

Supplied in a pack of 100, these transparent bags are suitable for classroom demonstrations and group science investigations.
