oh, thanks =P

gas is explosive in a closed container?

No... Gas needs a certain amount of oxygen in the air to ignite

I've hear of one where you take a Spalding ping-pong ball. (i guess it has to be Spalding dude to the chem. make up of it.) and you cut a slit in it and fill it with Drano. then you wrap the ball in electrical tape. you put the ball in some ones gas tank. the gas eats at the electrical tape and judging by how much tape you used depend on the time it take for the gas to get to the Drano. then boom. i personally haven't experimented with Drano and gas but it hear they are very reactive. so this would be a deadly prank based on the time that the reaction happened.

I think a grenade would be just as effective :S

thats way to much work for a prank. id rather just stab the tank.. fast,safe,and effective

Flash powder works better, and you dont need to "sear" the hole shut, just put a dab of glue on it. Gasoline wouldn't be "deadly", it would only pop the bulb and spray gasoline everywhere, by that time I'm sure whoever turned on the light would get everyone out before it burns the place down. Secondly, "back in Nam", gooks did not have camps with electrical wiring in them, they used gas lanterns. Lastly, why would they go through that much effort to pull a prank on them if they are ALREADY in their camp? I'd honestly just slaughter them in their sleep. Bullshit award goes to you fucktard.

Here's a deadly brilliant "prank":

Take a sponge (make sure it is REAL, not synthetic) and soak it in a saturated starch solution. Squeeze it down into a small ball and tie it with a string around so it will keep its shape until it is completely dry.

Remove the string once it is dry. Have 2 bags of chemical; sodium cyanide and citric acid. Drop the sponge ball down the target's toilet, and push it down just out of sight using something like a coat hanger.

Pour the citric acid in the bowl, and pour the cyanide in the water tank. Use enough of the chemicals to make sure it is a saturated solution for maximum effect. Don't use any other acids, you want to use citric because the odor/color won't give it away. Cyanide goes in the tank because it reacts with water and trace amounts of hydrogen cyanide can be detected if it wasn't sealed in the tank.

What happens basically is that the sponge expands to clog the toilet, and keeps the chemicals in bowl. When the target/victim flushes the toilet, the cyanide solution in the tank flows to the bowl where it reacts with the citric acid and it forms Hydrogen Cyanide gas. The concentration will be immense enough that the victim will die instantly, and anyone else in the bathroom will die as well. Pretty much anyone who enters the bathroom will probably die as well.

Feel free to test this using vinegar and baking soda instead of the chemicals, and you can use a plunger instead a sponge too.

Pretty effective when done right, and if caution is properly taken near impossible to trace.

Also if idiots try this, 2 words: gas mask.

LOL, I will keep this in mind when I start crossing off names in my black book. Very nice.
