To produce the 'hot air' that goes inside the balloon to make it fly.
If you had a hole in your hot air balloon you would not be able to fly it. it just would not float. It wouldn't float because when people are ready to fly it they power up the balloon they light fire in it. So if you have a hole in your hot air balloon the fire lighting inside of it would just go through the hole. You would have to buy another one. Sincerely, Einstein.
it can fly because the fire that comes out of the back of the rocket is its thrust.So when the fire comes out the back it causes the rocket to thrust forward.Remember the fire comes out with a lot of force thats why the rocket is able to fly because of the thrust. The body of the rocket is a device that can stay in space and float in there which allows the rocket to stay in space. The fire thrusts the rocket up but only to get out of earths atmosphere because earth has gravity space doesn't. In space the rocket does the rest of the work which is floating in a place without gravity. hope this helped!
well when they lift off they have this mass of fire expolding the ground which it makes it fly.
to see the flag fly in the dark cuz it is so important
small , it has a small light like bulb in the butt
Some animals that produce light are called bioluminiscent eg fire fly .
the boy fire fly has his light sticking out
All light fixtures are vented in some way to keep the heat differentials from producing pressure gradients. i.e. so that the materials around the light does not catch on fire. Flies, generally insects 'fly towards the light/heat source' and are persistent enough to find a way in.
you can get grass in all the Meadows and in fire fly light up
A male firefly has the"light" but the females do not
i got the fire fly by breeding fire and lightning
Fireflies create their light - by means of a chemical reaction taking place inside their bodies.
with its wings?!
When you light leaves on fire, there is a very high possibility that they will fly away and set any and everything around it on fire, too. In some places, it's against the law to burn leaves.(especially at certain times of the year)
Many insects use the position of the Sun as a navigation tool. If a source of light is bright enough and contains ultraviolet light, the insect will be confused by it and believing it is the Sun, will start to fly in progressivly smaller circles around the light source as it tries to navigate. This effect is used by electric fly killers which use a UV light to attract flys to the lamp which is behind an electrically charged mesh of wires. The fly navigates into the lamp but is electrocuted by the mesh.
Because they fly, and they light up, so especially before electric lights, it seemed like they were tiny flames in the air. :)
