In this instructable, you will learn how make a cool, fun, and harmless explosion that is a cool party trick. All you need for this Instructable is a piece of white paper, scissors, and a regular cigarette lighter.

Step 1: Making a square

Many of you probably already know this trick, but just in case you dont, this is how you make a square out of a regular peice of printer paper.

First take the top right corner and fold it over untill the top of the paper meets the left side.

Next you need to take the bottom peoce of paper that is hanging out and cut with your scissors across the line of the flap. Then unfold and you have a square.

Step 2: The triangle

This is hard to describe, but what i did was i made a pyramid and then i pushed two side into it untill they met. Then you lay it flat so it looks like a paper triangle.

Step 3: Folding

Now you want to take the bottom corners and meet them with the top point. You need to do this on the right and left side, then turn it over and do the right and left side again.

Step 4: More folding

Now the paper should look like the first picture. Now, you want to take the right and left corners and fold them into the middle. Then, turn over and do the same on the other side.

Step 5: A little more folding...

Now, the previously folded flaps should have an openning on one side. Take the bottem flap and insert it into the opening. Do this on all sides.

Step 6: UN folding...

Now you should be able to unfold it to were it looks like and X. There should be a small hole on one side. You may want to cut the hole a little bigger. Next you need to blow up the "balloon" so it looks like picture two.

so hold the balloon vertical wen u put gas in a nd light it? does the gas rise i take it?

Butane is actually heavier than air so it sinks...

I have actually never tried it vertical but know that you say it it does make a lot more sense. :) I always put it on the ground for safety reasons.
Sometimes I go crazy with these, I spray butane from a butane refill and light that. It is crazy fun.
i made a flamethrower out of butane cans by pressing the nozzle in...

Couldn't you also spray some perfume or Axe in there as it's also flammable? Or does it have to be lighter fluid from the lighter.
chardster (author)  Ananand5 years ago
never thought about that, but it seems like it would work fine.
Actually, that only works if it's at the right ratio of air-to-liquid, which it would settle out of pretty quickly. Lighter fluid actually ignites even if it was absorbed into something.
dont forget, however, that the fluid inside of these lighters is actually pressurized butane and becomes a gas as soon as it released from the lighter. So the lighter 'fluid' isn't fluid in this situation, it is gaseous butane.

I don't understand step 3. It would be nice if someone would help me out.

It was really hard to get it to light. I'll have to get a better lighter and try another night. I've been making those inflatable boxes for years though, so insulation on the folding quality of the box probably isn't the problem. In the end, I set two paper boxes on fire and walked away with almost the same satisfaction.

Haha, Thats what you do if all you have is matches:)

its just as easy to do this by using your fist instead of a box... it doesn't burn you at all, it just makes a fireball in your hand

THATS FREAKEN SWEET
Great. I done it at 1A.M. here, really fast funny hand movies at the video xD
supersaddy6 years ago
cool. ive seen people do that but instead of filling it with gas, you fill it with water and throw it at ur friends!

A video of it flying would be really nice.

In the mean-time, try this version from YouTube:


chardster (author)  Kiteman6 years ago
Wow nice video. Did you make it?
No, I just found it when I was looking for something else.

cool! but its more of a rocket than an explosion
chardster (author)  budsiskos6 years ago
Your probably right, but i thought of it as an explosion inside the ballon to propel itself.
Awesome! It's like doing the fireball, but in this box. Great job, gotta try this sometime.
