| The Truth about Jeans and Duct TapeSeptember 14 2002 at 12:07 PM No score for this post | matt (Login ChiliCheeseFries) | |
| The goal of this experiment was to accuratly test and report on the effects of wrapping a gun in a material in hopes to prevent shrapnel from explosions.
The materials used were 20 feet of schedule 40 2 inch pipe, cut into 10 1 foot sections, with a cap glued to each end. A valve was inserted into the side of the gun and the two electrodes were inserted. All materials were purchased at lowes.
Each "test chamber" was filled with 4% acetlyne and 96% oxygen. (is that the right ratio?) and i understand that it was abut at 4 psi. each chamber was then wrapped in something, jeans, tape, jeans and laquer, tape and jeans, wire mesh and jeans, wire mesh and tape.
Each test chamber was placed in a metal box, and a paper box (wire walls, and butchers paper) was inserted over the chamber. the wires to the ignition set up were run 25 feet away and each chamber was detonated.
The result from each detonition were recorded.
Nothing: The shrapnel obliterated 3 sides of the paper box and bounced around. Valve was found still in large chunk of pvc.
Jeans: The pipe fragmented and shredded the jeans, sending shrapnel through all sides of the paper box, and the fill-valve put a large dent in the metal box.
Duct Tape: Almost similar to the jeans, except the tape was nearly impossible to find, it fragmented with the pipe, and barely any large pieces of paper were found.
Jeans and Tape: Nothing different from the jeans except the fill-valve was not found.
Jeans with Methylene Chloride: this was probably the second worse one there is. Methylene Chloride is a solvent for plastic, and we soaked the thing in it and let it dry before firing. There was no paper bigger than 1 cm^2 and there were at least 50 dents in the box. the fill-up valve broke a hole in the bottom fo the box.
Jeans with wire mesh: same as jeans, valve was not found.
Tape and wire mesh: wire mesh broke off during firing and the effect was same as tape.
Jeans, wire mesh and Methylene Chloride- same as jeans and Methylene Chloride, the wire mesh seems to split along the line opposite to where its saudered together.
jeans+Methylene Chloride wrapped in tape+layer of mesh+another layer of tape+ another layer of jeans with Methylene Chloride- this was the worst. it blew out a side of our box, thus ending the experiment, and the valve shot through the opposite side and nearly killed mike (my neighbor who was watching) | |
