Demonstrate that although the mass and volume for each example are different, the density and specific gravity will remain the same. Includes 12 aluminum cylinders (1/2 in. dia.) of various lengths in a wood storage block.
Demonstrate the mechanics of fluid by visually comparing the viscosity of four different liquids. Each tube contains a different weight liquid and a 3/8 in. plated steel ball. The balls are lifted just above the line on the tube with a magnet and then released. Students compare the time for the balls to fall. Liquids are not included. Comes with…
A simple apparatus for demonstrating thermal expansion. The apparatus consists of a brass ball and ring. The cold ball passes through the ring but does not pass when heated. The brass ball is connected to the rod with a chain.

Heavy duty, both ball, and ring are mounted on separate handles. When cool, the 25 mm brass ball passes easily through the matching brass ring; when hot, it won't go through.
To illustrate the expansion of the metal on heating and contraction on cooling, a steel bar of length 100 x 10 mm and a plated brass gauge with a cutout to accommodate the bar and two holes through which the bar passes when cold.

To Investigate the relationship between the speed of a fluid and its pressure. Consists of a glass Venturi tube with two different diameters. One pair holds a U-shaped tube in which a color liquid can be placed to demonstrate the different pressures exerted when air is blown through the tube. It includes two rubber tubes and a glass Venturi tube…
Build rockets from ordinary plastic soda bottles that can soar to heights in excess of 150 feet! All you need is water! This solid aluminum bottle rocket launcher allows you to pressurize any plastic soda bottle (from 500 ml to 2 liters) with an ordinary bicycle tire pump. A quick tug on the release cord and your rocket climb skyward.…
Consists of an airtight plastic syringe supported between two wood blocks. Placing various weights on the upper block compresses the gas, allowing pressure and volume measurements to be made to verify Boyles Law.
This precise apparatus is designed for demonstrating Boyle’s Law (elasticity of gases). The apparatus illustrates accurate readings over a wide range of pressure. Two glass tubes, one with a closed top and the other with an open one connected together by a piece of flexible tubing, running parallel to one another on metal rods. This allows one of the tubes…
Two metals of different heat coefficients, brass & iron are laminated together and mounted in a wooden handle. This device demonstrates the unequal expansion of different metals by bending when heated. 200 x 25 mm.
Demonstrates the effect of temperature on the density of a liquid. Consists of a 3" stainless steel hollow sphere weighted so it will float when placed in cool water (15° C) and sink in warm water (30° C). Instructions include 3 experiments.
Set of different half-inch diameter specimens of varying lengths, supplied in a wood storage block. The set includes cylinders of Aluminum, Brass, Copper, Glass, Hard Rubber, Delrin, PVC, Acrylic, Teflon, Nylon, Maple, and Pinewood.
