Step 1: What You Need

You will need:
A canning jar with a steel lid,
A soldering iron,
Some solder,
A few centimeters of Brass pipe,
A Drill,
A drill bit of the same size of the brass pipe

Step 2: Let's Begin

Drill a hole through the lid and sand some of the paint around the hole away for soldering

Solder the Brass pipe into the hole using some solder and the soldering iron at about 35°C (662°F)

Step 4: Finished

Now just screw the lid on and hook it up to your vacuum pump (I use a modified bike pump which reaches up to 20mbar of absolute vacuum pressure)

Step 5: Safety

I don't take any responsibility for damages or injuries for example if the jar implodes. if you are using anything bigger than 500ml as a vacuum chamber, please make sure that the first time(s) you try it, you put it in a container or use safety gear in case it implodes to me minimize the risk of injuries.
