I did an experiment on the bench ... and forgot to turn OFF the 120V BURNER !!!
The TEMP went up to 260 degrees !
It belched out steam and the HODCELL BELCHED OUT the CC FOAM / WATER from the SS Canister into the bubbler !
I quickly opened the VENT valve to let the pressure escape.
I turned off the burner... and then backed away 20 feet ... awaiting an explosion ...
Luckily .. nothing blew...
