I do not want to purchase a canister of helium. How can I inflate my foil balloon?
There are shops selling balloons that also offer a balloon-filling service, even for balloons bought elsewhere. However, it may be best to call them first to confirm this and not have a wasted journey!
Many foil balloons can be inflated with air using a straw; however, the balloon will not float independently. It would need to be suspended from the ceiling or high furniture using the tabs at the top of the balloon.
