Hi~!

where did you get that hand powered pump? Also is it strong enough to make ice?

Where did you get the pump from?

Are there plans on how to make?

I'm trying to create a new type of manual food freeze dryer and need the vacuum to remove moisture.

Thanks in advance. Great video!

when you release the pump and the pressure becomes normal in the flask, does the water temperature stay hot or does it drop immediately @_@

[coolphysicsvideos]

@dpsrush water doesn't get hot. It's temperature stays the same all time. If the air pressure decreases the water's boiling point also decreases.

@coolphysicsvideos But if the water isn't hot, does this method have any effect once the pressure is back to normal?

What is the psig vacuum to make the water boil?

[superguko]

its boiling but its not hot because you just use pressure to make the water boil

How long before all the oxygen is depleted? Did you oxygenate the water prior to this project? How many cranks did you have to crank? I am working on a scuba project. Is there any difference between fresh and salt water? I know lots of q's. Thanks for the video. 5 stars
