Look Ma’ – no hands – air pressure science experiment

Riding a bicycle with no hands on the handle bars

The pushing force of air is called air pressure. The closer you are to Earth, the greater the air pressure. The farther away from Earth (in other words the higher your altitude), the less the air pressure. And remember, pressure is coming from all around us. Here’s an experiment to demonstrate the pressure of air…

Can we please lower the pressure in here? Bernoulli Principle science experiment.

An illustration of the incorrect equal transit-time explanation of airfoil lift

Named after Daniel Bernoulli, the Bernoulli Principle states that as the velocity of a fluid increases, a decrease in pressure occurs. The mathematician Daniel discovered many new ideas regarding fluids and pressure. For instance, Bernoulli, who had earlier begun to study medicine, wanted to know about the relationship between the rate of blood flow and…

A sucker’s bet – atmospheric pressure science experiment.

Red or pink drinking straws in a container

Funny how we take everyday activities for granted. Take for instance – sucking through a straw. Have you ever stopped to think about how we are able to suck liquids through a straw? What exactly makes the liquid climb up the straw and into our mouths? Well, we know you’re just itching to know so…

Vibrating pennies – conduction science experiment

United States One Cent Obverse penny

Remember – heat causes things to expand (or get larger). Cold causes things to contract (or get smaller). The heat from your hands is transferred through conduction to the air in the bottle warming the air. This causes the air molecules to move faster which makes the penny jump.
