Surface Reaction (soap and pepper) | This demonstration shows what happens to the surface when you put a drop of soap in water. |
| 2A20.10 | |
Capillary Tubes | This is a set of capillary tubes of various diameters used to show capillary rise with water. |

Pascal's vases | This shows that the liquid pressure is the same for any given depth below the surface, regardless of the shape of the containing vessel. |
| 2B30.10 | |
Crush the Can (Vacuum pump method) | This demonstration shows atmospheric pressure. |
| 2B30.30 | |
Magdeburg Hemispheres | This demonstration shows the force of atmospheric pressure. |
| 2B30.50 | |
Lift a Stool | When you pull on the handle, the volume of the air pocket increases and pressure decreases. The decrease in pressure on the top, combined with atmospheric pressure on the bottom, is enough to lift the stool. |

Archimedes' principle (Weigh Submerged Block) | This demonstration illustrates that the boyant force on an object is equal to the weight of the water displaced. |
| 2C10.10 | |
Velocity of Efflux | This demonstration shows that the velocity of the water stream is faster at the bottom. |
| 2C20.30 | |
Floating Ball (Bernoulli's principle) | Using a stream of air, you can make a ball "float" inside the stream. A variation of this is to attach a funnel to the hose. Put the ping pong ball near the inside of the funnel and it will get sucked in, even though the air is moving out of the funnel. |

Density balls in beans (density differentiation) | This demonstration illustrates the fluid properties of granular systems. |
