Chuck them on your campfire.
I was witness to a terrible outcome as kid.
We often used to muck about with lighting a fire in the field/woods by the river. Some clever clogs would chuck chunks of corrugated asbestos roofing (yes that was in the early ‘90s) and nervously wait for the pockets of gas witching to buildup and blow the stud apart.
Then one day this kid did bring a canister of toilet freshener that he’d nicked from his nans toilet. He’d seen somebody spraying and lighting the mist at same time, and it was fun.
After multiple lightups, the clever clogs had thrown the now “empty” can into the fire. Not sure what he was thinking, but he then decided to pick it up from the edge of the fire and presumably throw it in the middle.As he picked it up with his index and thumb protected by a sleeve of a jumper, the fecking thing blew up! Taking his thumb and finger along for a flight.
My only guess, that the sudden change in ambient temperature surrounding the can, had weakened it, followed by

The entire group did get bollocking from everybody’s parents. Lucky I wasn’t the eldest in the group, so did not end up being held responsible for the outcome and getting the ultimate Bollocking. The family of the eldest lad in the group ended up moving away, never to be seen again.
So no, chucking it in a fire could be disastrous especially in close proximity to a tent, etc.
PS:
We used to lay a trail of contact adhesive from a tube (Soviet name was “Moment”), then light it up at one end and watch it burn up leaving a hard trail of blackened hard glue along a footpath

Weirdly I was never attracted to sniffing it. To this day I am not a fan of the smell.
