Helium balloons are a great party decoration that add pizzazz to an event. They come in specialty shapes and themes, numbers, letters and of course the traditional round shape in every color imaginable. If you’ve ever purchased helium balloons for an event, you know the cost of this party favor can add up quickly. After buying the balloons you also have to pay to fill them with helium so they float fancifully for your guests. Faced with this expense recently for a party, I discovered a person can actually buy a helium tank from party supply stores, and even Walmart. But is filling helium balloons yourself cheaper?
Helium has an atomic number of two and a symbol of He on the periodic table. Pure helium is not toxic, and exposure to the clear, odorless, and tasteless gas should not pose a health risk. However, excessive inhalation of the gas can be dangerous, as it will act as an asphyxiate. In addition, when inhaled directly from a pressurized tank, it ma. The Helium Hotspot is designed to provide a long-range wireless network for low-power sensors and trackers, giving you the chance to help build a decentralised Internet of Things network. Helium is a noble gas, which means each helium atom has a full valence electron shell. Because helium atoms are stable on their own, they don't form chemical bonds with other atoms. So, helium balloons are filled with lots of tiny helium atoms. Regular balloons are filled with air, which is mostly nitrogen and oxygen.
Let’s compare the cost of paying to have a party supply store fill a helium balloon vs buying a helium tank and filling helium balloons yourself. For this example, I’m comparing the price of the helium only although it’s worth mentioning do-it-yourself tanks usually come with their own balloons, whereas having them pre-filled requires you to purchase the balloons as well.
Helium Balloons Filled At Store
I checked several stores including party supply stores and even a popular discount dollar store. The price of $1 to fill a common balloon was standard. Filling larger Mylar balloons usually cost more.
It would cost $50 to have 50 nine inch balloons filled for me.
Helium Balloons Filled At Home
The best price I found for helium tanks was the Unique Helium Balloon Tank sold at Walmart. A tank that would fill 50 nine inch balloons is priced at $34
Filling 50 nine inch balloons myself would cost $34.
What Happens When The Balloons Get Bigger?
At first glance, it would appear that buying my own helium tank and filling the balloons myself would be cheaper. In the example of filling 50 nine inch balloons, buying my own tank is $16 cheaper
But, if I wanted a little bigger balloon, the analysis begins to change. The helium tank from Walmart fills 50 nine inch balloons, but only 26 twelve inch balloons. To fill 50 balloons twelve inches in size, I would have to buy two tanks for a total cost of $68. The cost to have a store fill them remains the same, $50, as they charge the same to fill an twleve inch balloon as a nine inch balloon. In this case, having the store fill them is actually cheaper!
Commercial Tank Rental
Helium tanks are also available from rental places. Sizes range from tanks that will fill 30-50 twelve inch balloons all the way up to one that vill 400. Below are some prices and sizes available from a rental shop in the Twin Cities:
- 65 twelve inch balloons: $64
- 130 twelve inch balloons: $119
- 250 twelve inch balloons: $195
- 400 twelve inch balloons : $259
As you can see, as the tank gets larger, the price per balloon gets much less. For the largest tank the price per balloon dips to $0.63.
How Much is Your Time Worth?
When cost comparing two options, one must always take time and effort into account. If you’ve ever tried blowing up and tying up dozens of balloons, you know this is a mundane and frustrating task. My personal success rate for tying a balloon without breaking it is much lower than 100%.
The cost of filling helium balloons can add up quickly, so it’s natural for people to look for ways to save money. For the average party, even if the helium itself is cheaper than having it filled at a store, having someone fill it for you may be worth the expense. For a high quantity of balloons you have to take into account how the tank will be used, and if you are willing to spend the time and energy.
How about you clever friends, have you ever filled your own helium balloons?
