Balloons are one of the vital ingredients for a successful kid’s party. They come in all shapes and sizes, which will transform any room into a vibrant setting for the celebration to take place. A large cake and plenty of presents will help to make the child’s special day successful, as well.
One of the greatest joys for any child is trying to catch balloons as they float off into the air. A simple party game could be to see which child can blow their balloon up the fastest before tying it to a piece of string and letting it float.
People might be wondering how helium balloons in Perth actually work. The science behind this is pretty simple. Read on in order to learn much more.
Blowing Up The Balloon
Blowing up the balloon is the first step in getting it to float. There are a couple of ways to do this: people might want to blow the balloons up manually by forcing air into them through their mouths. This can leave some people out of breath, so be careful not to get too winded.
The easier option is to use a helium canister. Helium is the gas that allows the balloon to float in the air. The canisters are relatively inexpensive. These canisters should only be operated by a responsible adult because inhaling the gas can be dangerous and children might think that the canister is a toy. The balloon will rapidly be filled with helium. Choose helium balloons by Balloons Abuzz in order to get the party started.
How Does The Balloon Float?
Floating the balloon is possible because of the helium that is trapped inside. The helium gas is lighter than the air around the outside of the balloon, causing the balloon to rise effortlessly. Helium weighs approximately 0.1785 grams per litre. A litre of air weighs one gram. The laws of buoyancy mean that the lighter helium rises above the heavier air.
Filling up the balloon with as much helium as possible without popping it is the best way to ensure that it floats for as long as possible.
Why Do Balloons Start To Deflate?
From what you have just read, you might be wondering why balloons don’t just stay up forever when they are filled with helium. The answer is that the rubber develops tiny pores as it is stretched by the expansion inside. This causes the helium atoms inside to start escaping slowly over a period of time. The balloon will start to shrink, but it can be reinflated by putting more helium inside.
Air molecules find their way into the balloon as the helium molecules are escaping, which ensures that the balloon will stay inflated for a longer period.
As this article has shown, the science behind helium is very simple. Anyone who is inflating balloons should keep in mind that helium canisters should be kept away from children.
