Spray can as resistor venting vigorously and on fire

Two spray cans were set up as load resistors in an electrical circuit.
First set up was at 24 Volts tap, basically a dead short at 400 Amps at a couple of volts.
Second test was from the 6 Volts tap at 300 Amps.
The audio of the venting is quiet good and some nice flames erupt from the cans under test.
