How To Fill Foil Letter and Number Balloons


Be mindful that some letters do not take their full shape until inflated. For example, A "B" may look like a "C" until inflated or a "O" may look like a "U".

  1. Locate the filling tab on your balloon. This is toward the bottom of the balloon.
  2. When you locate the filling tab, slip a standard drinking straw in between the 2 layers of plastic. Then, insert your straw until you break the inner seal, which is about 1–2 inches. You’ll feel the seal snap as you insert the straw
  3. Blow into the end of the straw to fill the balloon with air. When the balloon is firm to the touch, it has enough air. Be careful not to blow too much air into the balloon. If you keep blowing, the balloon will eventually pop.
  4. When the balloon is full of air, Remove the straw and pinch the filling tab between to fingers to close it up. Doing this automatically secures your balloon, as the filling tab is self-sealing.
