How does Fix-a-Flat work?
The famous yellow Fix-a-Flat can contains both a liquid tire sealant and a small amount of air. When you push the button, the air in the can forces the tire sealant into your tire. Once inside your tire, the sealant seeks out the puncture and seals it up, while your tire continues to fill with enough air to get the rim off the ground.
