MethaneFlameAnother classic variant on burning/exploding gas.

A large coffee tin has a hole punched in the lid and another hole punched in the base. The gas is lit at the hole in the lid.

As it burns down, air is drawn in through the hole in the bottom.

Eventually the air/methan mixture reaches the right ratio and the mixture explodes inside the tin, blowing the lid off.
