i connected a plastic tube about 7 or 8 inchs long onto a butane can im wondering if when i push down on the can and put a match near it can the fire go back into the can and make the can explode and if so how can i stop that from happening and y would it happened
The fire in this case is a reaction between butane from the can and oxygen from the air. If either one is missing, there can be no fire. The fire cannot propagate back up the tube, since the tube will be filled with pure butane, meaning there will be no oxygen in the tube.
