We've compiled a list of resources for you to use to help your party go smoothly. It includes Frequently Asked Questions, tips, a Balloon Calculator, and how to care for your tank and regulator.
We created a Balloon Calculator to help you decide which tank to choose for your event. If you would like to use it, simply select the size of the balloon in the left column and put the amount of balloons in the right column. It will add up the volume needed to fill those balloons, and suggest a tank size for you. This calculator estimates round latex balloons only.
This calculator should be considered a broad estimation. Volumes vary between balloon manufacturers and if the balloons are over/under filled. Because there are too many variables, Helium2Rent cannot guarantee all balloons will be filled by renting the suggested tank. Helium2Rent can only guarantee the volume in each tank is correct, that our equipment is in working order, and that our helium is 98% pure.
For reference, here are our 3 tank sizes and the volume of helium they contain.
Balloon Buddy: 27 cubic feet
Party Animal: 60 cubic feet
Show Stopper: 150 cubic feet
If you have a very large event and our tanks don't have enough helium, you can try our friends at PrimeHelium.com (for Houston only)
Frequently Asked Questions
How long do balloons float?
The float time for balloons vary depending on balloon size, quality of balloon and ambient temperature. Generally the bigger the balloon the longer it will float. Balloons 9" - 17" will last approximately 6-10 hours, while 36" or 5 foot balloons can last days. Foil balloons float the longest, possibly a week or more, this is due to their foil material which keeps helium from escaping.
Do I get refunded for the helium I did not use?
No. However if you purchase a tank you are entitled to keep the tank until all the helium has been used.
Where should I inflate my balloons?
Away from powerlines and in a well ventilated area. Under a low ceiling is a good idea in case balloons get away during tying, you can grab them easily.
Do helium tanks explode?
No, helium is non-flammable. Even in the event of a fire, the safety mechanism in a cylinder valve will release the built up pressure before the possibility of any danger.
