When you approach the bellows, they turn on.
Feel the air pressure they create.
Take one of the bottles and hold it in the air flow at an angle until it starts whistling.
Find a partner and play together with the three bottles!
Huh?!
The bottles don’t always whistle!
You will hear different pitches depending on the size of the bottle.
Wow!
Air turbulence is created as the channel of air meets the edge of the bottle, making the air inside the bottle start resonating. We hear this resonance as a note. The air resonates faster or slower depending on the length of the bottle, which leads to a change in pitch.
