Yesterday, I blogged about the release of Popular Science columnist Theo Gray's new book, MAD SCIENCE.

In today's episode of Boing Boing Video, a collaboration with PopSci, we debut the world-premiere of the first video documenting an experiment like the ones you'll find in this book -- in which Theo cuts steel with bacon. It's a FLAMING BACON LANCE OF DEATH.

Yes, that's right, using nothing but bacon -- okay, prosciutto -- and an air hose, Mr. Gray constructs a high performance thermic lance that seriously cuts sheet metal.

In this video, you'll also see a purely VEGAN THERMIC LANCE built from one cucumber and several dozen thin vegetable-oil coated breadsticks. (Tip: the performance is all about the oil). This hotrod burns fast and furious, but does not last long enough to initiate a cut in steel sheet. The flame front travels towards the back of the cucumber and endangers the operator when it reaches the rubber connector.


Gray also created a CUCUMBER-BEEFSTICK LANCE. A high-performance thermic lance constructed from seven beefsticks and a cucumber. Later versions used Pup-Peroni brand dog treats, which are exactly like beef sticks only cheaper.

In some ways this device out-performed the Bacon Lance, and it's much easier to build.

But it's not made of bacon.

Theo tells Boing Boing,

"Cucumber is an *excellent* base for these things because it's air-tight, moist (to resist fire), easy to core, and has a rubbery skin that makes an air tight seal. About the only thing wrong with cucumbers is that they are not made of bacon. (I have a thing called a "fruit coring tool" which is like a very small round cookie cutter on a stick. You drill it down the middle of the cucumber until it comes out the other end, then stuff the cucumber with the chosen fuel.)"

    The spinning at 1:05 is mesmerizing.

    All he did was make a nozzle to direct the gas. O2 is gonna burn…the bacon is doing absolutely nothing but directing the gas…

    Hey look I made a car using nothing but bacon!(well all I did was cover a car in bacon but I can still say its a car made of bacon right?)

    Once you get the steel red-hot -and any fuel burning in pure oxygen will be hot enough- all you need is the jet of oxygen. The steel itself becomes the fuel.

    Look i know that prosciutto and bacon are similar, but let us not just flip flop the words around like it doesn’t matter. If that were actually bacon you would probably end up with cooked bacon at the end making this WAY better. I will say still cool.

    Prosciutto is ham not bacon. And expensive ham for the most part.

    #12 – Correct, exactly what I was thinking while watching

    #13 Derp… Yeah oxygen burns by itself man, for sure. Hurr durr.

  9. Enochrewt says:

    #6: And yummy. But yes, also very expensive as far as deli meats go. Prosciutto is ~$25 per pound for the average consumer.

    Time for the meatsitck…

    Disturbing, gross, funny, and enlightening … who could ask for more? :) :) :)

    #15 It’s the fire that burns, the oxygen just keeps it going, and the bacon just directs it. You’re fucking retarded if you think the bacon has anything to do with the fire except for containing it.

    This is: (count them) 10 LEVELS OF AWESOME.

    This man is my hero. Screw the jaws of life- I ever get in an accident, I’m calling Theodore Gray to cut me out of the car with some tasty, tasty prosciutto.

    The amount of bacon innovation going on never ceases to amaze me. Between the Bacon Explosion, Squeeze Bacon in a bottle and this, I feel like there should be a venture fund around this. Excuse me while I buy a bunch of pork bellies… (Javaun Moradi)
