Do you fill the balloon to the full 20 feet to get max altitude or under inflate it ? I know they expand with altitude.

Honestly, I guessed. Tried to inflate until I had 1.5 ratio. https://youtu.be/rtGyvikyzBQ

You under inflate it. I filled it to 5ft diameter and it got to 98.000 ft with a payload os about 600g

You should under inflate it to about a 6' diameter. Measure the shadow it casts to get an approximation. As it ascends the helium will expand the balloon to the 20' diameter before it bursts.

Yes the best way to inflate this is by buying a small air pump, I have a coleman one that I bought at walmart for $20 that works perfect to blow up all our inflatables.(would take a long time to blow up by mouth :) )

The pump is not air-tight enough to inflate the balloons with just air. You can pump the balloon up to walnut-size, that's it.

Hi! Inflating balloons with this pump results in balloons that stay on the ground. If you want your balloons to float, you could purchase a Balloon Time Tank that has helium, which causes the balloons to float.

If you do not release them until the warm air has filled the balloon, they will lift and fly until they burn out which is quite sometime. We released over the ocean shore at night and watched until they were specks in the sky. Hope this helps. Releasing them to soon will result in a fall to earth without lift at all.

We've launched a dozen or so and they last about 5 minutes. As for coming down in a grassy field, it's kind of self-correcting: as long as the flame is lit, there's heat that keeps it at a good altitude. Only when the flame goes out does the balloon come down. Nevertheless, any responsible/intelligent person wouldn't launch one of these things in drought conditions. By the way, do consider the metal ring that forms the base of the balloon. I expect it's kind of annoying for anyone who finds one of those things in their yard. The balloons can travel about a mile, depending on the wind - so take that into consideration, as well.

Yes. You can inflate two balloons at the same time. The inflator has two nozzles.

We had an air pump at the hotel and they blew it up for us. The second time I let the kids blow it up they are 12 and 13. I think it's harder to deflate. lol. Good luck and enjoy

If you use an electric inflator for air mattresses it will only inflate so far. Those types of inflators don't have enough force. The instructions say not to use a commercial air system such as an air compressor because they are too strong. According to the instructions one should use a foot or hand operated, manual pump to completly inflate the ball. I used an air mattress pump to the point it stopped adding additional air and then completed the process with a $3.00 foot pump. It worked beautifully and completely filled the bladder to the outer cover. Hope this helps. Our youth love it!!!

Use an air mattress pump or an inflatable boat pump. After fully inflated this devise works great. No need to poke a hole anywhere. There has to be sufficient pressure on the valve in order to open it.

Ours came inflated to the correct pressure. You can pump it up with a standard inflating needle and pump.

This is 65' inflated and it will take a long time to inflate this ball. There are small pockets that must be inflated properly with a hand pump or a foot pump. It will take some time and doing and in my case my sons were excited after each pocket was filled. It is fun though and worth the expierence for the kids and will tire them out.

Your ball is underinflated. If I remember correctly you should inflate until ball is 22 inches in diameter.At that size your problem will be solved.Reread instructions.

I use a pressure gauge and pump the inflatable to the manufactures specification. I find that this is the best way. I don't loose very much air when disconnecting the pump providing you perform the operation quickly.

It is like filling an air mattress. The best way to fill is with a shop vac or electric inflator due to size.

I used an air pump. Never saw where it said otherwise. Took a matter if seconds to inflate.

It needs to be inflated with helium. You receive it flat, you need to add air.
