Jack-o-lanterns stuffed with tea candles are for amateurs. Exploding pumpkins is where it’s really at—for trained professionals in fireproof lab settings, that is.

At the Royal Institution in the UK, scientists are celebrating Halloween by testing how pumpkins mix with thermite, a pyrotechnic. When rust and aluminum powder mix together, the reaction releases a magnificent amount of heat (more than 3600° F), turning the rust into molten iron. Inside a carved pumpkin, this creates quite the horror show. 

The lesson here: chemists have the best Halloweens.
