Would these fire in lower oxygen environments? We want to launch a small rocket from 100k feet above sea level.

It is possible, these are blackpowder motors and thus contain both fuel and oxidizer, and ignition is electrical. I think the real issue is will an electric match ignite at that altitude. But, depending on where you live, this use could possibly require government approval/licensing (http://www.flyrockets.com/regulations.asp) The regulations are determined by fuel payload but correspond to attainable altitudes. An A size engine only gives you 1-2.5 N s of thrust at any rate so I don't think you would get much out of these for your apparent objective of getting something into space.

I live in Houston, which can't be that much more above sea level, and we didn't have any problems.

:) If you live 100,000 (100k) feet above sea level, I'd like to visit your place. :) 100 Ft, will make no real difference.

Agreed with the other answers. Big concern would be how much exposure to the sun it would get at that level.

Once they take lift and are rising, the burn out far up in the sky. Once out, they drift down extinguished with no fire. The key to not causing a fire is the LIFT OFF and that is dependent of wind, and temp differences. I have had better lanterns than these but I would give them 4 of 5 stars.

No.. you have to buy the engine's. Wich I bought and ignighters just kept frying. Never got the rocket off the ground.

I believe it would work at lower pressure, since it gives a very high jet stream.

The D size rocket engine from Estes is my favorite. The C works well too, but the rockets does not go up as far; that's what I use on breezey days so I d't loose my rocket!

With the recommended engine this will reach an altitude of about 400 feet. If you modify it to accept larger motors it can conceivably reach about 1000 feet. With a model like this it's not always about how high it will fly, but how well it flies and returns that makes it a fun rocket to launch. The other thing that makes this model is taking the time to build a reasonable replica of the real thing - that's what makes it truly impressive.

I can't see any reason why not. They certain generate a heck of a lot less heat and in a globe, they should be protected against the elements.

As long as you can make fire at that kind of elevation then the hand warmer will work. Also this thing requires low oxygen flow so it should work at that kind of elevation but I never use this at that kind of elevation. So in theory it should work.

You can stay dry, no problem. The rocket launches with a bicycle pump that you use your foot to pump. The hose tubing puts you about 8 ft or so away from the rocket.

Maybe at very short distance. I think you would need the power of a pellet for distances over 5 feet

You can do it either way. We do a test fire with air only to see if the fins, nose cone etc stay on at firing. Then we add water to get distance or height.

They have a special coffee maker for high altitudes. This model shpuld work for 4,000 or more feet above sea level : BUNN BXBD Velocity Brew High Altitude 10-Cup Home Brewer, Black

The rockets are foam, therefore they go very high. We are not sure if a golf ball will go high, however you could definitely put it on top of the tube as it is smaller than the golf ball.

Good question, but something you would have to check with the manufacturer about, I only use it at sea level.

Any stove is going to work at elevations, just not as well the higher you go. For high elevations, I recommend using fuels that need little oxygen to burn. But I am no pro at low oxygen environments.

Hello Kellie, I have used them in sub-zero temperatures up here in Fairbanks, Alaska. They worked just fine, even better because the warm air will rise faster in the colder air. You can assist the lift off by filling the lantern using a hair dryer if you wanter, but that is not necessary.Good Luck!EAmon
