Bob Davis has made another can crusher with a huge 5 thousand volt power supply eBay score. A 100uF capacitor doesn’t sound that big, heck I have ones that are 10 times that size in a tray right beside me as I type this. Well the big difference is the one that is beside me has a voltage rating of 50 volts. That is a far cry from the 5000 volt rating that the one in this power supply! We have featured a bunch of Bob’s can crushers here in the past but I think that this is the biggest and baddest one so far!

Yay for 2.5 joules!
October 20th, 2009
Oops I meant 2.5 kJ’s

What’s the smoke from? I’m guessing the friction from the rapid bending melted some coating?

That’s sick! I love it. Now I’m dying to know what would happen to a body part in there. Not some morbid curiosity, but wondering to be clear.
October 21st, 2009
Could someone explain the science behind that? I’m having trouble grasping how a can can be crushed just by being in a magnetic field.
October 22nd, 2009
not to be sick or anything but could the coil be fitted over the head and used as a form of death sentence? Has Bob tried putting a piece of meat in the coil?

They use something called rapid transcranial magnetic stimulation (RTMS) to treat depression and migranes. Maybe this would work too???? I an not going to try putting my body parts in there! Maybe I will destroy a pumpkin in my next video!!!

Hi Bob,
That exploding pumpkin video would be great! I would love to see it.

IMPRESSIVE! One thing though – I recall from my technical school days that energy (in joules) is equal to one-half of capacitance times the voltage squared. Expanding this equation, Energy (joules)=0.5 x 0.0001 Farads x 5000 Volts x 5000 Volts, which is ONLY 1,250 joules (sorry Anthony). This formula can be found 3/4 of the way down the page at http://www.patentstorm.us/patents/4233835/description.html

This is nowhere near the biggest and baddest can crusher ever made.
My can crusher will tear can in 2 pieces with just 1/4 of total power (14000V 2kJ charge, cant go higher because work coil will explode)

Here is what 30000V charge did to watermelon

So I’m not the only one interested in knowing how this would affect organic matter when placed inside the coil. the watermelon is not a good example since the voltage was pumped directly into the melon. But it was a nice explosion none the less.

Wow Kizmox,
Those are some great videos! I love the watermelon one!!!

Hi Pouncer,
I wonder if a hot dog would make for a good simulation. I would be interested to see what would happen. I am guessing nothing since there is no metal in it but I am not sure. Only thing that might be hard is to prevent the hot dog from getting damaged from a flying coil wire.

Great collection, I never saw such products… are you on Twitter, so that I can follow you.

[...] 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 tried blowing up a pumpkin but I had to fill it with water first and then it still did not explode….
