Can you make a vacuum chamber?
Building a vacuum chamber gives you a fun way to do experiments at home, as well as do things like degas silicone or stabilize brittle wood. For a simple vacuum chamber to conduct a few small experiments, try a mason jar version with a vacuum pump. While this will create a vacuum chamber, it won't be very high-powered.

Can you use glass for a vacuum chamber?
Vacuum packaging in glass works as follows: take a glass jar with a sealing ring in the lid. Put your product in the glass and close the lid of the jar. ... The chamber is then decompressed and the lid of the jar automatically presses onto the glass jar, because of the pressure difference between the jar and the chamber.
Why do vacuums implode?
The most common method of accidental vacuums inside of tanks is caused by steam (water vapor). ... Now you have a little bit of liquid inside the tank instead of a large volume of water vapor. This decreases the internal pressure enough to cause a catastrophic collapse.Jan 18, 2016
How do vacuums not collapse?
The lower the altitude, the higher the air pressure; thus, as you move higher, the air pressure decreases. In fact, at the upper limits of the atmosphere, the air pressure reduces to basically nil. And since there's no real air pressure to speak of up there, then there is no force pushing the air into the empty space.May 16, 2017
How thick does a vacuum chamber need to be?
A rule of thumb is that the thickness of a stainless-steel circular tube should be at least one hundredth of its diameter (safety factor included).
How do you make a homemade vacuum chamber?
- Cut a circle in the top of the mason jar that will just fit the rubber stopper.
- Insert the rubber stopper into the top of the jar.
- Place a candy, such as a peep into the jar.
- Screw the top on tight.
- Place the nozzle of the pump into the jar through the stopper.
- Evacuate the air from the jar.
