Have some extra soda cans laying around the lab, that are taking up too much space? Instead of just smashing them with your boot, why not build an electromagnetic crushing machine to implode them, using a high voltage source and some large capacitors? That’s exactly what Bob Davis has been doing with his can crushers.

Actually, I can think of a lot of reasons why one wouldn’t want to do this, especially the big safety one. It looks cool though, and slightly less complicated than the coin shrinker. [via hacked gadgets]

    I would have disconnected everything BEFORE touching that can… it looks like he didn’t even check it was off, and not accidently recharging.

      Maybe he’s hoping to become a super hero?

    So, all of that just to crush the centre of a can. I can crush a can better using my bare hands and it’d be safer.

    My eyes kept being drawn to the ceramic Cocker Spaniel top, left in the frame. Does that make me a bad person?

      I think it’s funny that you can hear news coverage of the Heene family in Colorado on the TV in the background as he filmed this…

    Ummmm…. For those of us without a Physics degree, a little info on why this works would be cool… o.O

    We’re a technology projects site. That’s what we focus on. If we had to go through the websites of everybody whose projects we link to and approve of everything the person espouses, it would take us forever, and whose morality would we apply? — we have differing opinions on things here at MAKE, some of them vastly different. What we all agree on is the joy of making, so that’s our brief.

    We’ve gotten grief in the past for linking to sites where the makers espouse extreme leftie views — and we let those stand. The same applies here.

    You lot are the reason for pathetic laws that leave people with no options…!
    Cool gadgets are often dangerous.
