Attach a bomb to your chest. And then activate it.

i read somewhere thet u can take birthday candles and use them to make wicks that last a long time.MUAHAHAHAHAHA...then u can tie a quarter stick to it.that'll wake up the whole damn school.just ask to go to the bathroom and do it. u will be in class when they go off, so they wont know it was you.

Uh... No. Just no.

get like 20 M80's or quarter sticks of dynomite .and a pack of non filterd ciggarettes. light all the ciggaretts at once to make it easier, get em lit good then put them all in the bathrooms n stuff ,away from anywhere anyone would smell the smoke, then stick the ciggarets on the fuses of all the m80's or whatever your useing.(bacsically for time) it should sound like the school is gettin bombed. lol Tons O' Fun

You happen to be one of the most distastefully annoying twats to come through here so far. IRA? Yeah, right. That explains why you live in the USA. Dipshit.

i love this ghost guy, quite a colorful character

Hey there aint anything wrong with the U.S.A. But I do have to agree with Ghost. And M80's are school girl shit man step it up a notch.

While it's not very interesting, I have an idea for you.

For example, for a loud noise followed by lots of smoke, try this:
Wrap a BIC lighter in duct tape. Make sure you do it tightly, with at least 5 or so layers... for this to work, the tape MUST catch fire and burn for at least 1 minute.
Place it in a locker, and spray it with your flammable aerosol of choice. Most people like axe for this, but I prefer silicon waterproofer, or 99% Iso alcohol.

Light it, close the locker, and walk away. You have about 10 seconds before the duct tape catches from the axe/waterproofer and begins to smoke.

After a minute or two, the lighter will explode. While exploding lighters generally only create a fireball about 3-4ft in diameter, containing it in a 2ftx1ft locker should make some noise.

The smoldering remains of your little entertainment device should put out quite a bit of nearly invisible smoke that smells absolutely horrible, maximizing its effectiveness while making it hard to trace to a particular locker.

Hope this helped; just rediscovered this forum after a few months of inactivity.

smelly smoke and an explosion sure to mess with any school lol ... and bunches of students

well, jenna bush wus just at my school doin a speech on her new book, and a few kids got expelled for running around yellin "BOMB" mainly cuz the secret service wus there and shit. but my school doesnt tolerate ANY of this shit. but a good idea wuld b, get some m80's and light em, and flush em down the toilets so they blow in the pipes
