To teach Pascal’s Law and application of hydraulic press. By alternately applying force on a large and small piston, students will experience the mechanical advantage of one over the other. This device can be used to discuss the many uses of hydraulics such as power steering, hydraulic jacks, shock absorbers and auto braking systems.

Periscope that allows the view of an obstructed field above or below the level of viewer. It is a Z shaped tube with mounted mirrors on both sides at 45° facing each other.

Comprising 8 cardboard boxes 150 x 100 x 100 mm each with hole, screen and lid, 50 sheets black paper 200 x 250 mm, one lamp, mounted on bulb holder with flexible wires and one packet of pins.

Students can quantitatively see how pressure on an object changes as it moves deeper under a fluid with this interactive density pressure manometer activity. A hollow drum covered with a rubber membrane is connected to an open end manometer. When the drum is pushed under water the pressure on the rubber membrane increases the pressure inside the tubing, causing the manometer fluid level to change. The kit includes a tall vertical container, rubber drum, tubing open end manometer and demonstration guide.

Right angle, polished faces, edges slightly beveled, 90°x45°x45°.
