Mainly because there is pressure inside the aerosol can. The aerosol cans will explode when the pressure reaches out of its limit, by heating or squeezing or whatever.

Pressure is exerted on the can, causing bulging at both ends; if the sealed can is left on the shelf indefinitely, eventually it may explode. Do not wait for that to happen.
Why do coke cans explode?

Can a can of paint explode?
Aerosol cans run the danger of exploding when exposed to excessive temperatures. As the temperature rises, pressures in the can increase and may cause them to burst.

How can you tell if canned food has botulism?
Symptoms may include the following:Double vision.Blurred vision.Drooping eyelids.Slurred speech.Difficulty swallowing.A thick-feeling tongue.Dry mouth.Muscle weakness.
What makes a can explode?
Exploding cans are likely due to refermentation after packaging, which creates an initial increase in carbonation made worse with elevated temperatures.
Can you kill botulism by cooking?
The toxin that Clostridium botulinum produces is among the most deadly food toxin known. Fortunately, heat destroys the toxin and cooking is the best way to control botulism.
Can you get sick from old canned food?
Canned foods are also sterile, so eating an expired can of tuna, for instance, won’t necessarily make you sick—it just won’t taste as good. That said, if the can is bulging, leaking, or hisses when opened, it may be contaminated with an extremely rare toxin that causes botulism, a potentially fatal foodborne illness.
Can canned food be left in hot car?

Can a Lysol can explode?
