How to Make a Smoke Ring Launcher
How can you make the invisible ring of air visible? With a
little smoke, of course. The best smoke rings are made by
filling the trash can with theatrical smoke. Smoke
machines (foggers) are commonly used in stage
productions. Check to see if your theater department has
one, or see if you can borrow one from the disc jockey
who plays for your school dances.
The best smoke rings are also made by gently tapping the
shower curtain. A hard smack results in a fast blast of air
that is difficult to see. The flying vortices are best seen
against a dark background with light coming from either
side.

9. Does smoke rise or goes down?
On having burned the small tube it departs from the paper it
is clear in the shape of particles that, together with the gases
that formed in the combustion and the air they formthe
smoke.
In normal circumstances, the smoke ascends dragged by
the warm air of the combustion.
In our experiment, the smoke that takes place is produced in
the interior part of the small tube travels along it. Inside the
bottle, there is no warm air, so that, when the smoke goes out
for the low end of the small tube there aren’t produced rising
currents of convection and the smoke, denser that the air, it
rushes to the bottom of the bottle.

Feria Mundial de Ciencias de Google
La feria de ciencias de Google ha comenzado. Y Google
cree que fomentar la competencia en el campo de las
ciencias así como se fomenta en los deportes o en la
música, sobre todo en los mas jóvenes, es el verdadero
futuro. Por lo que junto a CERN, The LEGO
Group, National Geographic and Scientific
American idearon la Google Science Fair, La Feria de
Ciencias de Google en la que los participantes deberán
tener entre 13 y 18 años y el único requisito es tener una
computadora, una conexión a internet y un navegador.
