Ok this might seem confusing but basically I bet these 7th graders that I can create a huge explosion using the simple fart over a lighter technique. They dont believe me and now I have to prove them wrong.

Heres my current plan

I turn on a lighter right next to my asshole thats primed up for a juicy fart. I fart but then right below me somehow I will have a small explosion device that will go off nysnc with the fart. I was wondering what kind of substances I will need to make the device and if its even possible to make a device so small yet so explosive that a 7th graders eyes will believe that my asshole farting caused this.

I know this thread seems really trollish/stupid but its actually a true bet I got into with them. I was also wondering if this is in anyway dangerous? Should I be worried when mixing the substances? Alright thanks for reading

um....this is a really really bad idea. anything that is going to make a huge fireball is going to A) burn your ass B)be easy to see and C) has a chance of going wrong and cooking your nuts. really...the best idea here to to say you lied..because doing anything like this will end up badly

Wow...

shove a can of flammable aerosol up your ass. learn to control spray with anal contractions. I think its your only hope.

No really, there isn't much you can do without injuring yourself or losing the bet. Take your pick

Inject some butane or something up there. Make sure to get a vid.

This is a very bad idea indeed.

I suggest just forging a video.
