Explanation:
the past we have been asked why balloons (often found in supermarkets) sometimes carry a ‘Not suitable for helium-filling’ warning. Contrary to popular belief, it’s not that they’re dangerous when filled with helium, it’s simply because they’re too small to float. So, in theory, all balloons CAN be filled with helium but not all of them will float! To avoid disappointment and unnecessary cost, read on to find out which balloons float and which don’t…
The general rule of thumb is that small balloons won’t float or if they do, it won’t be for very long! This is because the small amount of helium that you can fit in them won’t be enough to overcome the weight of the material the balloon is made of. Every gram counts when you are trying to get a balloon lighter than air and the size of each balloon as well as the type of material they are made of will play a crucial part in the amount of weight each balloon can lift.

Latex
Latex is a light material so you will be ok helium-filling balloon sizes that measure 9 inch and upwards. If you want your latex balloons to float for more than a couple of hours, then steer-clear of 5 inch round balloons, 6 inch heart-shaped latex and 6 inch QuickLink balloons as they are just too small. Also all modelling balloons, whether they are 160Q, 260Q, 321Q or 350Q are only suitable for air-filling as they don’t have the capacity to hold enough helium to float.
Foil
Whilst the ‘small balloons won’t float’ rule also applies to foil balloons, other factors play a part. A standard foil balloon measures 18 inches in diameter (round, heart and square) or 20 inches (star) and will float with helium. Anything less than this is unlikely to float, especially if it is a shaped foil. This is because foil is heavier than latex so requires more helium (and the capacity to hold the helium) to lift it. To demonstrate, our 16 inch numbers & letters and 14 inch animal foils are for air-filling only as the shape of them means a reduced capacity to hold enough helium to float even though they’re not much smaller in size than a standard foil balloon.
As with all rules, there are often exceptions. Beware too of some of the larger, more complex foil shapes such as the 34 inch Hashtag balloon: The Hashtag is made up of multiple small pockets which fill when inflated but overall the balloon cannot be filled with enough helium to overcome the weight of the foil material. The percentage sign on the other hand has a lot more overall gas capacity so will float no problem.

The Elf on the Shelf balloon is another example. Although this guy measures 29 inches when inflated, he is made from multiple smaller balloons that will not float. When you put them all together; the whole elf balloon has too much weight in the foil walls and too little overall gas capacity to float. That’s ok though as the Elf looks cute sitting on a mantelpiece or shelf when air-filled
Answer:
Helium Information
Helium (He) is required to make balloons float. Helium is an inert, naturally occurring gas that is lighter than air. You can hire helium cylinders suitable for inflating large quantities of balloons or to inflate just a few balloons, party helium tanks are available to buy.
