Introduction: Celebrate Your Love...

...any excuse for an explosion!

Step 1: A Little Delicate Work.

Take a decent-sized tin with a fairly snug lid.

Use a hammer and a nail to punch a hole in the middle of the lid and the bottom of the tin. Use the same hammer to flatten the sharp bits (health and safety, don'tcha know).

Step 2: Just Do It!

Use a handy (unlit) bunsen as a delivery tube to give a good dose of methane to the tin (about 20 seconds).

Stand the tin on something that lets air get to the hole underneath (if you don't have a tripod in your laboratory, or you don't have a laboratory of your own, use two bricks side-by-side with a gap between).

Wave a lighter over the top hole. The gas will light.

Watch the flame. As long as you can see the flame, it will just burn like a lamp. Eventually, though, the flame will turn blue, shrink, and disappear down into the tin.

At that point... >>>BANG!<<<

ooo yeh my dad has like three blowtorches! didnt they do this on mythbusters though? with pringles?

They did something like this, but with hydrogen and oxygen.

Lol isnt methane fart.... hey i dont have a butane thing, do u know how else i can do this?

You could fart in the tin? Methane is also mains gas, which is what I used. If you can't pipe mains gas to the tin, then you do really need to buy a blowtorch and use that (unlit) to fill the tin.

Even more fun when the kids go home and I have the lab to myself!

I did this years ago with old Tupperware, butane and a match on a stick :P


How it works:

When you fill the container with gas, you also displace oxygen (from air) required for combustion. Slowly, the gas escapes out of the top hole which can be lighted like a gas lamp. As the gas escaped, oxygen slowly enters the container through the bottom hole until the air/fuel mixture becomes combustible. At this point, Ka-boom :)

you see the one where, just for fun, they bubbled some methane up through soapy waater then lighted the foam?
