How do you make a vacuum chamber?

Procedure:

1. Cut a circle in the top of the mason jar that will just fit the rubber stopper.
2. Insert the rubber stopper into the top of the jar.
3. Place a candy, such as a peep into the jar.
4. Screw the top on tight.
5. Place the nozzle of the pump into the jar through the stopper.
6. Evacuate the air from the jar.

How do you build a vacuum?

The most common way of creating a vacuum is to pump the gas out of a vessel that is initially at atmospheric pressure. There are many different ways of pumping on a vessel, but all of them have a limiting pressure below which they are ineffective.

How does a vacuum chamber work?

Vacuum chambers work by removing air and gases from a vessel or chamber through a vacuum pump, creating a vacuum, which is defined as a space completely devoid of matter. The pump does not reach out, grab a molecule from the chamber, and suck it in.

What can you put in a vacuum chamber?

Demonstrations

1. Balloon. A good place to start is with a simple balloon.
2. Marshmallow. A standard marshmallow or seasonal marshmallow based candy is made of a material with lots of little air pockets.
3. Shaving cream. Shaving cream similarly has tiny pockets of air and an expandable volume.
4. Boiling water.

What is laboratory vacuum?

Vacuum is used for many standard appli- cations in the preparation and processing of samples. In most cases, the vacuum is not the focus, but plays an essential supporting role. the most familiar lab vacuum applications are filtration and drying.

How do you make wood stabilized?

Wood stabilization is the process of strengthening wood so that it will no longer respond to changes in humidity. Stabilization can be performed in five steps: drying the wood, loading the vacuum chamber, saturating the wood with resin, curing the wood, and coloring the wood.
