How to Make a Grease Bomb

What are just a few things that come to mind when you think multi day rafting trip? Desolate beaches perhaps? Caveman style technology? Motivated groups of danger seeking risk takers? Excessive amounts of bacon grease? If any of this sounds familiar, chances are you've gone rafting.

One of the biggest pyro displays one can pull off on a river trip is something called a grease bomb. Using a hot fire, a good amount of bacon grease, and some water, the little (or big) pyromaniac in us all can come out and play.

When executed correctly, the simple ingredients hurl a massive fireball skyward, produce squeals of enjoyment from the peanut gallery, and show your group a safe display of what happens when you show complete disregard for that age old saying of "don't pour water on a grease fire".

**Warning this Instructable involves fire, explosions, bacon grease, and danger. If you'd like to do another project involving copious amounts of bacon grease with a much lower danger factor, check out How to Make Bacon Soap. Grease bombs can be very dangerous and should only be done by experienced bacon grease pyrotechnicians. When done correctly they are a real good time.**

Step 1 Gather Grease

The first ingredient to a grease bomb is grease itself. You'll need a good amount of it - around 1 1/2 to 2 cups worth. The more grease you have, the bigger the bomb. Once you've done a small one, you might want to try making a grease bomb that uses more grease - around 3, 4 or more cups of grease ups the anti.

On the river we collect grease from bacon. Trip guests love bacon - so that means that we're usually cooking up POUNDS of the stuff on each trip. Each pound yields about 1/4 to 1/3 of a cup of grease, so collect all the grease you can until you've got about 2 cups worth.

Any fatty meat will produce good grease, so try rendering grease from different sources and see which produces the biggest fireball. (Anyone who can speak to the flammability of different types of animal fats please speak up).

After cooking the bacon, I let the grease cool. Then, I place a coffee filter on top of a non-breakable sealing container and pour the grease through. If your grease has little bits of meat in it, it won't work as well and it will splatter and sputter as you heat it. The coffee filter takes out all of those impurities and results in wonderful amber clear grease.

For future refrence wax does that way better get one of those bucket type citronella candle from a hardware store put on fire till its completlymolten/on fire, then put some water in even a spoonful make a notible fireball and a cupful is insane. Use appropriate caustion of course.

Nice noah! Im assuming Tim Anderson had something to do with this? Are there alterante ways of doing this, other than different fats? -PKT

[rreneti]

like ur pix lol hahahahaha

[awa213]

hey rangi wat uhp mola mola mola moola molllllllllaaa

[noahw]

Nope - this is straight from my involvement in the white water rafting community. An amazing group of DIY problem solvers by their own right, that have absolutely no internet presence or documentation what so ever...well, besides this Instructable of course.

[PKTraceur]

What other kinds of DIY? -PKT

[Jonny 5]

How is that classed as a bomb? Just looked like a chip pan fire to me. Rubbish.

[awa213]
