Ever have one of those cans of tomato soup that don't seem to want to come out of the can? Reddit user drmario422 found that if you puncture the bottom of the can, the soup falls straight out every time.
This is essentially shotgunning a can of soup. When you puncture the can, it creates an extra hole for the air to flow through and canned soups can fall straight out of the can. As you're shoving a sharp object into a tin can, we'd recommend you try this with caution, but if you ever really need to get all of the tomato soup this might be your best bet.
