Mylar balloons are made of a thin, metalized plastic film. They are often used for parties and other festive occasions because they are lightweight, inexpensive, and can be filled with either helium or air. Inflating mylar balloons is a relatively simple process, but there are a few things you need to know to do it safely and correctly.
The first thing you need to do is gather your materials. You will need a mylar balloon, a straw or balloon pump, and helium or air. If you are using helium, you will also need a helium tank. Once you have your materials, you can begin inflating the balloon.
