Mystery Hour Question

Is there any reason to shake aerosol cans to get all the contents out?

Morris, Hendon

Answer

Name: Louise, Warrington

Qualification: Fire extinguisher engineer

Answer: When you get to the last part of the contents of the canister, the particles settle on the bottom of the canister. The compressed air in the can needs to expel those particles, so the only way to get them to the top of the canister is to give it a shake.
