Description:   A dramatic visualization of air pressure. This 1000 ml bottle has a balloon attached to its neck and an additional hole in its base fitted with a rubber stopper. You cannot inflate the balloon with the stopper in place, but remove the stopper and the balloon easily inflates. Replace the stopper, fill the bottle with water, remove stopper and Whoosh! – a geyser erupts!

Description:   Investigate the dependence of pressure on a gas with changes in temperature and volume.

Description:   This bourdon style vacuum gauge features a 2" Dial with a range of 30-0" Hg.

Description:   This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.

Description:   Rectangular density set.

Description:   Hands on demomstration showing the power of a vacuum.

Description:   Dramatically Demonstrate that Temperature Increases with Pressure

Description:   Apparatus to study convection of gas.

Description:   Hands-on STEM learning kit for launching rockets using a simple chemical reaction.

Description:   This working model hydraulic/pneumatic jack shows how hydraulic or pneumatic systems can multiply forces.

Description:   These balls are the real deal: vivid contrast between elastic and inelastic collisions.

Description:   Perform a quick and easy quantitative verification of Boyle's Law.

Description:   A working gauge is mounted in a transparent case so the actual working parts are visible.

Description:   Everything needed to explore the relationship between pressure and volume of gas at constant temperatures.
