Moving eggs
Materials:
A raw egg
An egg boiled (10 minutes) and very careful not to break them.
Procedure:
Mix the eggs well, until you know what oil and what is hard. Now, put them to turnover a large area, or on the ground. Watch how they move, which turns more easily, faster, or longer. Now put the two to rotate at the same time. Stop them and drop them immediately. The raw eggstarts to spin again, because although its surface is stopped, the liquid inside kept spinning. Now you can do the same trick with the egg. Put it to turn very quickly and you'll notice the samephenomenon happens with traditional tops. If you get enough speed, instead of turning in bed, will rise.
The kin of the water
Materials:Water in a glass
a dropper
soap
paper
Talcum powder or cayenne
a thread
Procedure:
Take a pot dry, fill it with water almost to the top. With the dropper throw in as many droplets as possible,without spilling. You will see the water get above the rim (about 0.25 cm.) And this is due to water stress that keeps the molecules together. We call this the "skin" of water. Of course, the waterdoes not have "skin" of truth, but has a surface tension, as we will see in this experiment. Now try different objects float on the skin.
MYSTERIOUS MOVEMENT
What do we do?
Consider moving upand down a few mothballs in the midst of a liquid.
Materials:
Beaker or container
sand
agitator
spatula
Naphthalene balls
vinegar
sodium bicarbonate
distilled water
How do we do?
Itexamines, first, mothballs, if they were too smooth to the touch sanded a bit to be something rough. A then prepares a mixture of water and vinegar. Add a few teaspoons of baking soda, stir themixture and pour the mothballs.
The result is ...
The balls fall to the bottom of the glass initially but after a long rise to the surface of the liquid to fall again and so on.
