What is Air Molecules
Before learning about air pressure, we need to
understand a new terms – Air Molecule.
Air Molecules is super tiny particule surrounding us.
Gravity pulls the air molecules toward the earth.
The more condense of air molecules, the heavier they are.
The weigth of the air molecules all around us is called – the AIR PRESSURE.
Know more about Air Pressure
The weight of air pressure above a given area on Earth’s
surface is called Atmospheric Pressure. It can be measured
by an instrument called Barometer.
While how can we test the existance of Air Pressure at home?
Let’s have an simple experiment by using the bottle we provided for Turbo Racer.
How does it work?
It is magical, isn’t ? The reason why the water doesn’t
pour out is becasuse of Air Pressure. When we fill the bottle up
with water, all air inside has been squeezed out. The space inside
the bottle become vaccum. Air Pressure push the card towards
the mouth of bottle and thus aviod the water pouring out.
【GREEN ENERGY】The Turbo Racer is fully air pressure powered. This engineering kit doesn’t require any battery. The only thing you need is a small cross-head screwdriver for the assembly.
【HANDS-ON LEARNING】This STEM model introduces you to green energy and engineering concepts. Learn about atmospheric pressure and how it is related to us. The pressure indicator in the bottle shows the change of air pressure and the safety valve automatically release excess pressure.
【GREAT SCIENCE GIFT FOR CHILDREN】 Beautifully packaged, it is an ideal birthday or Christmas gift.It’s ideal for young science enthusiasts, especially those with an interest in physics and green energy.
