Helium can be transferred between foil balloons by inserting a straw into the valves of both balloons and pressing firmly on the helium-filled balloon. 


Please Note: You can only transfer helium to a Mylar balloon and do not inhale helium.


  1. Insert the majority of the straw into the helium-filled balloon. 
  2. Hold the neck as tight as possible to avoid helium from escaping. 
  3. The helium will pass through the straw and into the new balloon.
