This episode is marked explicit because we go into details that might lead to a person catching on fire. It’s interesting science and we don’t get graphic, but it might be too much for a younger listener.

If you are interested in the science of all things pyrophoric and don’t want the spontaneous human combustion content, listen until the 3:25 second mark.

Warning label for pyrophoric materials. Don’t cut off a truck with this on the side.
