Handmade honker
Sound is produced by vibrations.
What you need
- plastic cup
- drinking straw
- latex glove
- plasticine
- rubber band
What to do
- Half way up the side of the cup, make a small hole (about 2 mm diameter).
- Make another hole in the base of the cup, just big enough for the straw to slide through.
- Stretch the palm part of the latex glove over the mouth of the cup and fasten it by stretching the rubber band around the rim of the cup.
- Slide the straw through the base of the cup until it pushes against the latex glove. Use the plasticine to form a seal around the straw where it passes through the base of the cup.
- You can now play your handmade honker by blowing through the hole in the side of the cup.
What's happening?
The horn-like sound you hear is caused by vibrations made by air pushing under the latex to get out of the cup via the straw.
