Airzooka Air Cannon

Airzooka Air Cannon
The amazing Airzooka will blow you away! Blast a harmless vortex of air up to 6 meters towards any object or person. Then have a good giggle after you mess up a person's hair, ruffle their shirt, dress or papers unnoticed from a distance.

Explore the basic principles of chemical kinetics, with the fascinating oscillating reaction kit. Watch as a clear solution suddenly changes to amber, then to a deep blue/purple, then back to clear again. Be amazed, as the colour cycle repeats again and again.

In this remake of the Briggs-Rauscher reaction, or the classic 'oscillating clock' explore solutions, concentrations, catalysts, equilibrium and the use of controls and variables. It is a remarkable reaction, one-of-a-kind chemistry kit that is sure to excite your class, or scientist in training.

Age: 12+ with adult supervision. This science kit contains chemicals that can be harmful if used inappropriately.

What You Get

Fascinating Oscillating Rx Kit. Contains malonic acid (5 g), manganese sulfate (1 g), sodium iodate (5 g), sodium thiosulfate (10 g), sulfamic acis (5 g), starch solution (20 mL), wooden rack, pipet, stirrers, spoon, small scoops, cups, MSDS and instructions. Requires hydrogen peroxide (3%), not included. Magnetic stirrer will increase oscillations, but is not required.

How Does it Work?

Fascinating Oscillating Rx Kit presents a range of color changing effects through a fascinating chemical reaction. Simply mix the included solutions together, stir, then watch the color change within seconds. From dark blue to clear again, this wonderful experiment kit clearly demonstrates the principles of Briggs-Rauscher oscillating chemical reaction. Explore the effects of variables like temperature on chemical reactions.
