Foil balloons (MYLAR) are generally inflated with helium in order to have the appearance of floating balloons! The final result is very pretty, ideal for a surprise, for a birthday or simply for an evening!
Problem I don't have helium, what should I do?
It is possible to inflate mylar balloons without helium except that they will not fly, but you can very well stick them on the wall with a piece of double-sided tape!
How to inflate balloons? Very simple, you just need a simple plastic or cardboard straw, whatever. In order to inflate your balloon you will have to insert the straw at the level of the valve of your balloon then blow into the straw so that your balloon inflates.
Once your mylar balloon is well inflated, simply remove the straw and that's it!
No need to tie a knot, the mylar balloon valve closes automatically and prevents air from escaping from the balloon!
