How Do You Deflate Foil Balloons?
To deflate a foil balloon, you need to first release all the air that’s inside the balloon. Next, find the valve where the air was originally filled and insert a straw or a chopstick inside. Gently push the straw or the chopstick into the valve, allowing the air to escape. Press down on the balloon’s surface to help the air come out more easily. Once you’ve removed most of the air, carefully fold the balloon and store it for future use.
