How many liters of helium can this baloon hold?

I don't know about helium. We used them as water balloons for the kids to bounce on.

I'm not sure, it is a water balloon. If you want to fill one up with helium then I would recommend a 36 inch helium balloon, they have them here 36 Inch Latex Balloon Cool Blue (Premium Helium Quality) Pkg/1

The equation for the volume of a sphere is: V=4/3 &#960;r^3 (that weird n should be "pie" as in 3.14159) Thus, the volume of a 60-inch in diameter (30-inch radius) sphere is as follows: V=4/3 &#960;&#12310;(30 in)&#12311;^3((&#12310;2.54 cm)&#12311;^3)/&#12310;(1 inch)&#12311;^3 (1 mL)/&#12310;(1 cm)&#12311;^3 (1 L)/(1000 mL)=1853 Liters But, the volume of the balloon will depend on the pressure required to fill the balloon because the recoil force of the balloon will increase as the diameter increases. Basically, the pressure inside the balloon will be much higher than the surrounding air pressure. And the balloon pressure will increase significantly as the balloon diameter increases and approaches its burst pressure. So, the equation will be: (P1 (at sea level))/(P2 (needed to fill the balloon) )=V2/(V1(at sea level)) I work with angioplasty balloons (those used to treat blood vessel narrowings) daily and the burst pressure in those balloons is between 8 and 25 atmospheres for compliant and non-compliant balloons. This balloon is a compliant balloon (meaning that it changes shape with various pressures), so I would guess that the burst pressure is less than 8 atmospheres - probably more like 4 atmospheres. Thus: Volume =(4 atm)/(1 atm) x 1853 L=7,400 Liters (at atmospheric pressure) But, no fear, you don't have to fill the balloons to full capacity. By filling the balloons to only 40 inches in diameter, the volume and pressure will be substantially less. By my calculations, only 1100 Liters. As far as this information, you know what they say about experts: They know more and more about less and less until they know everything about nothing.

The helium tanks I buy from the party store come with about 30 balloons, but they're on the smaller side. However, I can't vouch for this amazon listing, as I didn't purchase this particular product from this seller. Sorry!

I purchased a helium tank from a welding supply company. Full instructions here: http://www.kb3vfe.com/2012/07/how-to-launch-weather-balloon-for.html

Excellent for helium balloons! They work wonderful and look beautiful. I highly recommend this product :)

If you want your balloons to hold up longer, there is a product called 'Hi Float' you can get and spray inside the helium balloon before blowing them up. I have had a problem with the helium itself, so I can't really tell how it works. One reviewer said that his balloon held the helium for 4 months after he used 'Hi Float'.

These particular balloons are made to be inflated with air, they are not large enough to inflate with helium and float. Balloons 9" or larger are manufactured to be filled with helium to float. Thank you.Thank you!

Well it would depend purely on the size of the balloon. I would say this parachute weighed approximately 7 or 8 ounces so I would think 3 normal sized helium balloons would lift it off the ground and carry it pretty high. Not sure of the intent here but I could see a pretty cool game with a air rifle.

Yes. I bought 2 for a party and thought I'd run out with just one, but there was plenty of helium in one tank to fill about 50 balloons. I was very happy with this purchase.

It is large enough to fill a Zippo lighter 2-3 times, so it should give you one fill on your handwarmer. You will find it is a temporary fill, because you will lose some to evaporation. I don't see its capacity listed anywhere, even on the Zippo website and I threw away the package.

"Tank" makes me think you are asking about helium not Hi-Float. A bottle as pictures (pint?) was enough for over 100 balloons for kids day at church and tablespoon or so left. We blew them up Fri. night and they were still floating at 100% thru Sat. The key is to squeeze the balloon after putting some inside so it coats the whole inside of the balloon. Each 9" balloon took about 1/4 to 1/2 teaspoon. Not sure how big a "really big" balloon is.

No, the helium is very light. Does not add much weight at all but only charges battery to 80%. I have had to warranty it already though.

I don't know really how to answer this question. The best way I can describe it is that we used about the same amount of helium as 3-4 large Mylar balloons. I would think a small tank that you purchase from the dollar store or Wal-Mart would fill it. We pay a yearly rental fee for our large helium tank so it is really hard to judge. I can tell you that our large tank filled 10 of these large air walker balloons plus several latex and Mylar balloons, and we still have plenty of helium left in the tank.

The listed capacity of the container is 20.0 Liters which is 5.28 gallons. If you were to fill the container to the top, you probably could fit around 5.5 gallons, but with gasoline, you want to leave some space for air and expansion. Gasoline has a high vapor pressure and filling this or any other gasoline container beyond it's recommended capacity IS DANGEROUS. DO NOT DO IT.

Not sure this balloon is durable enough to tie off for 3 days. It DOES NOT hold thousands of cf of helium. I used this balloon for a near space balloon project and used 150 cf of helium. Took a 4 lb payload to 70,000 feet!!

Yes, the head has it's own hole to be filled, the body also has a separate hole and the legs also, the balloon is nice just too much helium.

Yes. You can typically Google helium providers in your area. Get a regulator, a 1/2 inch piece of flexible hose, and a piece of PVC to fit inside the neck and hold it open. Stratostartv has great videos on youtube regarding how to do this.

Must have helium or it will not float upright. This balloon will last at least 3 days and is adorable! A small helium tank is around $50
