A new composition, method, and apparatus for sealing and inflating a flat tire are described. The new composition includes a gas-generating agent and an activator, along with a sealant. In use, a gas propellant is generated in situ when the gas-generating agent is mixed with the activator. For example, carbon dioxide is generated when carbonates, such as baking soda, and an acid are mixed. The carbon dioxide gas generated in this manner can inflate a flat tire to a desired pressure. In addition to carbon dioxide, nitrogen gas, noble gases, and nitrous oxide gas may also be used instead.
