Anyone know of good video's that demonstrate suck back during distillation?
I'm trying to show some people the effect of rapid cooling of gases and the effects it has on both sides of a system and I think distillation is a
great example of where this can happen - if you have any other ideas I'm open to suggestions.
I've seen video's of people boiling water in a 55gal drum, sealing it, and then spraying it with water allowing it to "implode", and that doesn't
really show how it effects both sides of a system where there is a heat source and a cooler side.
I'm thinking that another example might be steam hammer but that isn't quite the same as it relies on a wave of water being sucked or pushed as
basically a piston, though I guess it is a pretty similar example - what do you think?
Do you know any good video's that show this phenomenon?

grant thompson made a few years ago a video about it, he placed a glass bottle in the microwave with a few ml of water inside, then while steaming hot
he placed the mouth of the bottle under the water line in a container, and the water rushed in, he also used a drum IIRC.
another example would be the absorbtion of ammonia, it's too easy to get a suckback and ruin your experiment (if you didn't set up a vessel for the
fluid flowing back after the generator)

Generally suckback isn't an issue with distillation until you add a washbottle into the equation.

Or an aspirator! Definitely use a safety bottle and/or check valve with those.
