Nature of Liquid & Gas

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.

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.

Magdeburg Hemispheres - Cups

Two rubber vacuum cups with handles can be used as a simple but effective demonstration of the great force of air pressure. When the edges are placed together and the cups compressed to expel the t... More.

Boyle’s Law Apparatus

This apparatus allows students to investigate the elastic properties of a gas enclosed in a calibrated airtight syringe by subjecting the confined gas to various loads. The syringe is built into a ... 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.

Fire Syringe

Turn on to the 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 comp... 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.

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 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.
