We recommend that you don’t inflate illooms® with helium as they won’t float very well or for very long and we don’t want this to impact on your enjoyment of illooms®.
Latex is porous so helium leaks out of the balloons over time which influences how long they float for.
Also, the LED inside illooms® makes them weigh more than standard latex balloons which has an effect on how high they float.
