Lightweight, easy to use and reliable, Helium King is the UK's best selling Helium Cylinder.
This Helium Tank contains 0.42 Cubic metres of Pure Helium and will fill up to aproxinately:
· 50 x 9” latex balloons
· 25 x 11” latex balloons
· 18 x 12” latex balloons
· 18 to 20 x 18” foil balloons
· 3-4 x Large 34” foil numbers/letters (depending on shape)
Latex balloons are porous and have an average flotation time of around 6-8 hours depending on the size of the balloon and room temperature. Due to this we advise to inflate the balloons 1-2 hours before the party/event.
Treating latex balloons with Ultra Hi-Float (available separately), can make them float up to 25 times longer!
Float time of a foil balloon: 5+ days.
