Balloon propelled wooden toy car. Fit a balloon over the nozzle then blow into the exhaust pipe to inflate. Release the air in the balloon and watch the car go!
These scales are dual calibrated. Use grams for a mass activity and newtons for a force activity.
These scales are dual calibrated. Use grams for a mass activity and newtons for a force activity.
Traditional scales with zero adjuster, maximum capacity of 125kg with a 0.5kg resolution.
Demonstrated the Brownian Motion‚ or random motion of smoke particles. A specially designed plastic box has a sliding lid at the top and contains a glass smoke cell, a cylindrical condensing lens and a low voltage festoon
The set consists of two plastic, 10cm-diameter hemispheres. Each half has a wooden handle firmly attached to it. One of the hemispheres has a raised edge to hold a rubber seal, while the other hemisphere has a stopcock for attaching to vacuum tubi
