Can you re-inflate a foil balloon?
Due to the self-sealing valve on most foil balloons, it is possible to refill the balloon, either as a top-up or completely. After your celebration the helium can be removed from the balloon – gently insert a paper drinking straw into the valve of the balloon and slowly press the remaining gas out of the balloon. Fold the balloon and store it until the next occasion. Generally, a foil balloon can be re-inflated 2-3 times.
