Nature of Liquid & Gas

Surface Tension of Water

Explain the principle of high surface tension as water acts like a membrane stretched across the surface preventing the sulfur particles from sinking. A wetting agent lowers the surface tension and... More.

Pascal’s Ball

Easily demonstrate Pascal’s Law and show that water pressure transmits in all directions with this simple device. The device consists of a 3" hollow sphere with ten equidistant nozzles co... More.

Hydrostatic Studies Kit

This comprehensive kit explores critical concepts at a budget-friendly price. Show that a body immersed in water displaces its own volume of water and use this concept to measure irregular volumes.... More.

Fire Syringe

Turn on to Ideal Gas Law with this explosive demonstration! As air compresses, the temperature increases and combustible material bursts into flames. Also is great for discussing adiabatic c... More.

Little Shop of Physics – Pressure

This kit provides instructional materials which allows open-ended exploration of science concepts in a way that is engaging, exciting, and effective. Kit includes several “demos” that c... More.

“Charles Law Mechanics of Gas” Can with Lid

Demonstrate the forces of air pressure by boiling water in the can and allowing to cool. See the can get “crushed” right before your eyes. Metal can with lid, 1-1/4" opening. More.

Magdeburg Hemispheres – Spheres

Astonish your students with the force of air pressure. It takes 350 lbs. of force to pull these half-spheres apart after the air inside has been pumped out. Kit consists of two plastic hemispheres ... More.

Spouting Cylinder

Demonstrates that the pressure of a liquid depends on the depth/height. Huge, metal construction. Dimensions: 16-1/2" H x 3" dia. Base is 5-3/4". Baked stoving hammertone finish. More.

Nasco Speed of a Bubble Tube Set

An effective introduction to proper techniques of graphing and a powerful way to connect a physical science concept (velocity) with a mathematical idea (slope). Three transparent plastic tubes cont... More.

Nasco Buoyancy Experiment Kit

Will it float? Will it sink? Explore the factors that cause objects to float or sink. Students also experiment to investigate how shape and weight affect buoyancy. Kit contains: clear plastic box (... More.
