Hi all,
I was just wondering how I could recreate this at home
What parts do I need?
Thanks,
Harry

Well normally pulling a vacuum involves an implosion risk. That jar is not a good vacuum enclosure. But the simple water pump mechanism being used in the video pulls a pretty mild vacuum, so the implosion risk is probably minimal.cazzuey said:What are the safety risks?
berkeman said:Get the water pump thing, and use epoxy to fasten a nipple onto a jar lid, I guess. I'm surprised that it takes such a soft vacuum to cause the water to evaporate like that.

Borek said:Take a syringe - the larger, the better. Suck a bit of hot water inside, plug the hole (even with a finger), pull the piston. Water will boil instantly, even if for a very short period of time. That's exactly the same effect.
A water pump can get you near as low as the vapour pressure of water which is about 20 mbar while the outside pressure on the vessel is 1 bar.berkeman said:But the simple water pump mechanism being used in the video pulls a pretty mild vacuum, so the implosion risk is probably minimal.
In that case, this thread is closed.DrDu said:A water pump can get you near as low as the vapour pressure of water which is about 20 mbar while the outside pressure on the vessel is 1 bar.
Hence the pressure difference acting on the vessel is nearly 1 bar which is all what counts in terms of implosion risk. Even with a high vacuum pump it won't be higher.
To recreate the same pressure as in the boiling experiment, you will need a pressure vessel or chamber. This can be achieved by using a pressure cooker, a sealed container with a pressure gauge, or a vacuum chamber. The pressure will depend on the type of experiment and the desired results.
The materials you need will depend on the specific boiling experiment you are trying to recreate. However, some common materials may include a heat source (such as a stove or burner), a pressure vessel or chamber, a thermometer, and the materials to be boiled (such as water, oil, or other substances).
The temperature and pressure can be adjusted by controlling the heat source and monitoring the pressure gauge or thermometer. You can increase or decrease the heat source to raise or lower the temperature, and adjust the pressure by controlling the amount of gas or air in the pressure vessel.
Safety is always a top priority in any scientific experiment. When recreating a pressure boiling experiment, it is important to use caution when handling hot materials and equipment. Always wear appropriate protective gear, such as gloves and safety glasses, and follow all safety guidelines for the specific materials and equipment being used.
The ability to recreate this experiment at home will depend on the materials and equipment available to you. Some experiments may require specialized equipment or materials that may not be readily available in a household setting. It is important to carefully consider the safety and feasibility of conducting the experiment at home before proceeding.
