Air Pressure

The fuel from one rocket would run out before the complete distance is traveled and gravity could then still pull it back to earth. In this science experiment we will explore how one can make use of a two-stage...

The air around us has a lot of power especially when low and high pressure systems are created with it! Try to crush a tin can using only air pressure in the following science experiment and learn just how...

A fire cannot burn without air or 'oxygen'. A fire that is not burning well can often be helped along by blowing or fanning it, so that more air reaches the fire. Air or 'oxygen' is also used up...

What do crocodiles and bottles have in common? They both eat eggs! Have some fun with the following science experiment.

In the following science experiment we will put the ambient air pressure to good use, to make a water fountain powered by the force of air pressure.

Air makes grass or trees sway, moves the clouds around or trap water in a funnel by filling spaces that we perceive as empty. We will use the last example to illustrate this, in the following science experiment.

Have you ever watched a hot-air balloon and wondered how they stay up in the air so gracefully? Let's build our own hot-air balloon in the following science experiment and learn how these magnificent flying machines work.

Have you ever wondered how a sailboat can seemingly turn in any direction even though the wind only comes from one side? Let us do the following science experiment to better understand how a sailboat harness the power of...

Early windmills used the wind to turn blades that rotated grindstones inside a mill. Various grains such as wheat and corn were ground with these grindstones to produce flour for baking bread. These days, a type of 'windmill' is...

A rocket is a very powerful machine which obtains 'thrust' or 'propulsion' by ejecting a jet of fast moving fluid exhaust from its engine. In this science experiment we will explore how rockets are launched vertically and we will...
