The outside of the cylinder at the level of the Hoop (Fig. 1) in two diametrically opposite places, stick the two squares of paper with dimensions of 50×50 mm, and pierced holes for the holder burner — spokes made of steel wire with a diameter of 2 mm. In the role of a burner for heating the air inside the balloon protrudes from the tampon moistened with kerosene or alcohol cotton wool with a diameter of 50 — 60 mm, which is attached in the middle using a thin copper wire with a diameter of 0.3 mm. If the cotton is not secure, it can fall from the needles, to fall down and cause a fire.
Balloon launch can only be done in a quiet, calm weather, away from the forest, power lines and houses.
The launch of such a balloon to provide two. One holds him over the top at arm’s length, and the second caution wet cotton wool in kerosene and sets it on fire. Thus it is necessary to ensure that the kerosene did not get on clothing or shell of the cylinder.

1 —cover; 2—storage cylinder; 3—strut; 4—vise
Fig. 5. Burner:
1—bracket of steel wire; 2—wool, moistened with kerosene or alcohol; 3—braid of copper wire
After a few seconds the air in the balloon heats up, it will be lighter than air and will rise gradually up, leaving a dark streak of smoke.
While the kerosene is lit, the balloon will rise up. Only after the fire is out and the air inside the shell cools, the balloon will slowly decrease. For this reason, it is safe in the fire relation
Such balloons are frequently used in some countries, major holidays, and for public interest sometimes they give bizarre, even in the form of human figures.
Launched a high altitude balloon is heated during the flight often causes casual viewers because of its unusual view of the most incredible guesswork: what a gimmick is silently hovering in the sky? So not a UFO?
