This item is great for demonstrating that heavy and light objects fall at the same rate in a vacuum. It is made of a transparent tube 1.5″ (38 mm) outer Dia. and 40″ (1000 mm) long, with rubber end caps, one of which has a nozzle and stopcock with 14″ (355 mm) rubber tubing for connecting to a vacuum pump (not included, catalog Item #6080-00). The demonstration provides an illustration of the principles of gravity that leaves a lasting impression on students.
• Comes with a Teacher’s Guide
• Includes a simulated coin and a feather

• AmSci Exclusive
• Teacher's Guide Included
• Handout Included

Fit standard meter sticks with this clamp to set up a demonstration balance for studying principles of levers, moments, torque etc. It is made of spot-welded steel for durability. The clamp is designed for fastening to meter sticks by means of a knurled set screw and provides easy viewing of the meter stick.
• Comes with a removable metal wire stirrup which serves as a weight hanger when placed in an inverted position

WHEEL AND AXLE

Item 3556-00

$15.46

This item consists of spring-loaded metal device and 2 steel balls. It demonstrates that a ball released vertically will hit the floor at the same speed of a ball released horizontally. Use it for demonstrations in physics classes to show students Newton’s Second Law in action!
• Comes with Instructions

Item 3557-00

VERTICAL ACCELERATION DEMONSTRATOR

Item 3558-00

$15.46

This unit is a self-contained demonstration of color mixing. It has a convenient on/off switch and turn-knobs allow the user to precisely control individual light colors. Prepare for a visually stimulating illustration of light behavior!
• Comes with a Teacher’s Guide
• Made of plastic

Item 3559-00

$25.70

• Teacher's Guide Included
• Handout Included

Think you’re stronger than the air around you? Think again! When the air between these hemispheres is removed, the only thing keeping them together is the atmosphere around you, more than enough pressure to thwart even your strongest students! Use these hemispheres to demonstrate air pressure and vacuums. They are made of flexible synthetic rubber.

• 50 mm (2″) Dia.

Solid Drilled Zinc Ball, 1″

Item 3488-26

$2.23

For various applications in physics laboratory. A cast iron ball of 79mm diameter with two hooks on opposite ends. Enamel finish.

Item 3497-02

$22.14

Use this ball to demonstrate the effect of temperature on the density of a liquid. It consists of a copper ball about 3.54″ (90 mm) Dia., properly loaded so that its density is less than that of water, so it floats. When the water is heated, its density reduces and the ball sinks.

Specific Gravity Bottles, Uncalibrated 10ml

Item 3505-01

$1.55

These items are also called Density Bottles or R.D. Bottles. They are recommended for comparison purposes. The bottles are useful for illustrating physical properties such as density.
• Each bottle has a perforated stopper (about 0.03″ (1 mm) bore) and a ground mouth for a proper fit
• Made of borosilicate glass
• 25 ml

Item 3505-02

$1.90

All of our metal balls are great for physics experiments and demonstrations! Use them for density and volume measurements, pendulum bob, potential energy and conservation experiments, ballistics, and more. These small spheres make a useful addition to labs and classrooms.
• Made of aluminum
• Drilled
• 1″ (25 mm) Dia.
