What does space sound like?
Test it out using a bell inside a vacuum bell jar.
The vacuum bell jar comes with a bell which is connected to a 4-6 V power supply via the rubber bung supplied. Place the vacuum bell jar on a pump plate and extract the air using a vacuum pump.
Three classic demonstrations inside the vacuum bell jar:
- Sound the bell and listen.
- Insert a marshmallow and see it "change".
- Tie up a balloon (without blowing it up first) and place it under the jar.
Material: Plastic.
Dimensions: Inner diameter 14 cm. Height 30 cm.
Accessories: Pump plate (art.no: 53836) and vacuum pump (art.no: 53820) are ordered separately.
