Have you ever blown across a bottle's top and made a pleasant sound? Most of us know that when you blow in the bottle at a certain angle, the air is released from the bottle, creating a sound. The sounds can vary, according to the bottle.
An empty bottle creates a low sound and a full bottle creates a higher sound. These Belgian musicians/artists first tuned a juice bottle to find the right tones. Then they mirrored it to a drinking straw.
With this drinking straw, you can turn your juice bottle into a musical instrument. Imagine every straw becoming a 'bottle tuner'... all the bottles in the world would become musical instruments.
Check the video, where the musicians play Beethovens 5th symphony.
