Heat Convection in Fluids— Demonstration Kit
Dramatically show the effect of convec- tion currents in air with a lighted candle. Follow this up by observing convection currents created when a hot colored liquid rises and a cool clear liquid sinks. Includes comprehensive Teacher Notes for relating these phenomena to real-world convec- tion patterns, such as weather and ocean currents.

Cartesian Diver Construction— Super Value Kit
Students learn the relationship between pressure and air volume and how air volume acts to regulate buoyancy by constructing Cartesian divers made of simple equipment and materials. Procedures for constructing 11 different types of Cartesian divers are provided in a detailed write-up. Super Value Kit is complete with 100 pipets and hex nuts. Requires water and two-liter soda bottles. Includes Flinn Exclusive STEM Integration Guide!
Heat Transfer Kit
Students fill one insulated container with hot water and the other with cold water. Then they link the two containers with an aluminum heat transfer bar. Students record the temperature change of the water in the cups over time and relate the change to the associated heat transfer. Purchase one for use as a class demonstration or one for each laboratory group.

Breaking Board Paradox— Demonstration Kit
Simple, yet very dramatic demonstration of the connections between air pressure, surface and interia. A thin white pine stick is placed over the edge of a table. A sheet of tissue paper is placed over the stick and spread out on the table. When the over- hanging portion of the stick is hit sharply with a hammer, it breaks. The other end of the stick remains stationary and the paper is not torn. Students will be amazed at the results. Enough for 10 demonstrations.
Bottomless Bottle—Pascal’s Law Demonstration Kit
Dramatically demonstrate Pascal’s law of equal pressure and the incompressibility of fluids. Fill a glass bottle with water. Firmly grip the neck of the bottle, give the top
of the bottle a whack with a rubber mallet and—Pop! The bottom of the bottle drops out. The small force applied to the water in the narrow neck of the bottle becomes a much larger force on the bottle’s wider bottom—Pascal’s law in action! Includes demonstration instructions and enough glass bottles to perform the demonstration 12 times.

Centripetal Force—Classroom Set
Demonstrate the relationship between angular velocity and centripetal accelera- tion. The low cost and simple construction of the centripetal force apparatus make it a must for every classroom. The experiment uses the weight of 20 washers hanging from one end of a nylon thread to balance the pull of a rubber stopper swinging overhead. Complete instructions provided.
