Opal Passions - Helium Balloons & Chair Cover Hire, Slough, Berkshire.
How long will balloons last?
11” latex balloons last on average 11 hours filled with helium, and about 2-3 days when treated with Hi-Float. Foil balloons last approx. 5-7 days. Air-filled balloons generally last for a couple of weeks, but will not float.
What is Hi-Float?
Hi-Float is a liquid protective coating that is inserted into the balloon and spread around to prevent helium from escaping as quickly. It is water-soluble and non-toxic.
Why can’t I just have the balloons set-up up the day before my event?
If you are using foil balloons, you should have no problems. But latex balloons must be treated with Hi-Float in order to ensure that they float longer than 24 hours.
Do you charge a delivery fee and if so what is it?
Local Delivery and set up are free of charge.
Can you come to my event venue and tell me what I need?
Yes, we can provide a site survey.
Is helium flammable?
No, helium is not flammable, and therefore very safe to use.
Can I suck the helium out of a balloon and make my voice funny?
It can be fatal to suck helium from a balloon because it displaces the oxygen from your lungs! Do not under any circumstances allow children to use a helium tank without adult supervision!!
