Feeling pressured?

Great science experiment and classroom demonstration
.. we’re not constantly aware of the intense pressure pushing in on our bodies. (Would we really turn into mush in a vacuum? No… read more about the effects of a vacuum on the human body here). Thank goodness, because it’s quite startling. I know, because I’ve felt it, in this wonderful science classroom experiment.
All you need is a big trash bag and an industrial strength vacuum cleaner, and a willing victim (er, “faithful subject of science.”)
