1. Start by finding a flat surface to work on. It’s best to avoid sharp or pointed objects that could puncture the balloon.

2. Unfold the mylar balloon and locate the inflation valve. This is usually a small, round opening on the bottom of the balloon.

3. Attach the nozzle to the inflation valve if you have a balloon pump. If you’re using a helium tank, attach the valve to the inflation valve instead.

4. Hold the balloon by the bottom or neck, depending on your preference.

5. Inflate the balloon slowly and steadily, careful not to overinflate it. If you’re using a balloon pump, use short, quick bursts of air to avoid overinflating the balloon. 

If you’re using a helium tank, release the helium slowly and stop when the balloon feels full.

6. Check the balloon’s firmness by gently squeezing it. If it feels too soft, you may need to add more air. If it feels too firm, release air until it feels just right.

7. Remove the nozzle or valve from the inflation valve once the balloon is fully inflated.

8. Tie a knot in the neck of the balloon to seal it. Attach a string or ribbon to the knot if you plan to hang the balloon.

9. Adjust the balloon’s position by gently pulling or pushing it until it sits at the desired angle. But how do you blow up foil balloons with helium?
