A teabag (the type with a string attached) is carefully emptied of its tea and the string removed. It is upturned so it resembles a box or cylinder with the open end facing the surface of the heatproof mat. A taper or match is used to set fire to the very top of the teabag. The bag will slowly burn and after a few seconds should rise into the air.
Equipment typically required (per demonstration)
This demonstration may be conducted out of doors, however, even a very small amount of wind may disrupt the heating of the bag and it may not rise.
