Happy Birthday" foil balloon that measures 16 inches in size. These types of balloons are commonly available for birthday parties and celebrations. Air Volume: Foil balloons are not as flexible as latex balloons, and they can burst if overinflated. You can inflate them to about 90% full to allow for some expansion and prevent them from bursting. Use a Hand or Electric Pump: Inflating a foil balloon with air can be more challenging than with helium. You may need a hand pump or an electric pump designed for balloons to make the process easier. Sealing: Foil balloons typically have a self-sealing valve that will hold in the air once you stop inflating. Make sure the valve is securely closed to keep the balloon inflated.
