After watching mythbusters' "towering inferno" methane bubble feat. I wanted to recreate this project. however I lacked methane so I turned to the next best thing -- after noticing that there were two full tanks on the oxy-acet torch at my folks place. this bucket bomb sent the neighbors into panic a quarter mile away (just like they used to when I was in high school and had lots of free time on the farm). The first question out of my uncle's mouth after he came running from a quarter mile away was "where did you get the dynamite from"
Step 1: Materials
2 gallons water (any amount will work, just so the the bucket is about half full
oxygen/acetylene gas & torch head
Step 2: Method
I only filled the bucket with bubbles about 3" from the brim.. there could have only been 10 or 12" of bubbles, but it was more than enough
Step 3: Ignition
maybe I should have suggested no smoking in the last 2 steps... acetylene is a very flammable gas, when surrounded by oxygen, it makes for one heck of a KABLAM so no smoking would be a great idea...
my ignition system was very primitive. I ripped off a piece of cardboard lit it with a lighter, and tossed it over the top of the open bucket. I was standing about 4 feet away when I tossed it, and when it went off, (Im not sure if it was instinct or force but) I found myself on the ground.
I would like to point out a few things...
first off, depending on what kind of bucket you use might have some bearing on if the hospital can see via X-ray if you have foreign matter in your person. I have been told PVC and plastics dont register with a lot of lower-grade Xray machines... something to think about... Metal obviously shows up, but its not always a good idea for metal shrapnel
to go flying through your neighborhood
Secondly.. you may want a really really remote area to do this in, like I said, the neighbors came running
thirdly... I had no idea that the blast was going to be so furious... I was thinking it was going to be a small little fire-ball, and instead it wound up blowing my bucket to shreds... also the bucket was placed above ground and left a pretty good sized crater... DO NOT DO THIS IN YOUR GARAGE!!!
Finally Wear helmets, goggles, Kevlar, or anything you can get your hands on... I was deaf in one ear all day, and could barely hear out of the other... it was an extremely fun experiment but like I said, even if you gotta use a rubber, wear protection..
