Why does my gas can collapse?
6 min read
Asked by: Stanley Camacho
When fuel vapor is trapped inside a closed container without any way of escaping as it increases and decreases in volume and pressure, the laws of chemistry and physics tell us that it has to go somewhere. Here are some examples of gas cans that have collapsed in due to the change in cooler temperatures.
Why is my gas can imploding?
You’re not hearing air escaping, you’re hearing it rush into the container! If the container is crushing, it means the air that was inside the container is being absorbed by the liquid. The container is tightly sealed, so the external air pressure is crushing it to take up the space left by the disapearing air.

How long does gasoline last in a plastic gas can?
three to six months
Though it naturally degrades and loses combustibility over time due to oxidation (exposure to oxygen) and evaporation of its volatile compounds, gasoline usually lasts three to six months when properly stored in a labeled, tightly sealed plastic container or metal tank of the capacity recommended by your fire …
Why do new gas cans not have a vent?
Well, back in 2009, the Environmental Protection Agency banned the sale of gas cans that actually work well.
