1. SmokeFall

2. Question
 Why does the smoke fall down?

3. Hypothesis
 If we put on fire the paper, the smoke is going to fall
because there is no air only warm smoke coming
down.

4. Background Information
 www.youtube.com

5. Materials
 Empty bottle (has to be dried)
 Piece of paper
 Candle or lighter

6. Procedure
 Make a round whole on the bottle.
 Role the piece of paper.
 Put the rolled paper in the whole.
 Light up the paper with a candle or lighter.
 Keep the fire on.

 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.

10.  Science Fair Projects on Cigarette Smoking
 Science Project on Cigarette Smoking:

 Purpose: To see how smoking affects the lungs.
 Procedure: 2 jars made into siphon smoking machine.
A Sponge on end of the cigarette will act as lung.
 Conclusion: Smoking makes the lungs dirty.

12. Ferias Mundiales de Ciencia
 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.
