    Sorry all your stuff got stolen.

    I hope you can find the assholes that did it and kick them in the balls.

    Can you explain how and why the glass jar does not suck in and break..

    Our atmosphere exerts 14.696 psi ( or 1,520,000 microns) on everything at sea level. When we remove the pressure from inside the jar we only have 14.969 psi pushing on the jar from all sides. Jars are round as its very strong structurally, think arches on bridges.

    We use to collapse 55 gallon drums with a vacuum truck in the oil patch. Little bit scary the first time you see it happen. Sucks them flat down like a smashed beer can.

    Thinking about it we only ever did it to full drums as the liquid was being pulled out. It would probably only collapse the sides in if it was empty. Never tried an empty one.

    It would collapse empty ones too. A full one with liquid would be a hydraulic crush from with, same principals though.

    Im not a scientist but guessing its a combination of total surface area and leverage. Ie. A 200 man standing on the side of the drum may dent it, changing the shape out of round losing structural support, likely wouldnt affect the jar.

    Guessing at the math, an average 55 gallon drum is 22.5 diameter and 33.5 inches tall, the sides alone would have a surface area of roughly 1,590 square inches, each inch having 14.696 psi exerted on it for a total of roughly 23,336 lbs

    The jar used is maybe 7 inches round 12 inches tall, so about 264 square inches. So about 3880 lb total pressure. Again these are sides alone.

    I believe your micron math is a little off.

    Used an online calculator, maybe so

    760,000 microns was a case of differential it said, 1.5 million for vacuum purposes

    That's psi so you would start at zero. You kinda doubled it ;)
