Learn how even though air is invisible, it still has mass and can support very heavy objects under the right circumstances. The models in this kit use a unique blower motor and a safe, soft-bladed fan to drive a series of models. The blower motor uses an impeller to increase the air pressure under the hovercraft. The fan creates a stream of air to push the vehicle forward. Using these components, you can build and investigate the hovercraft and other machines that rely on air and air pressure to function. Construct a batting machine that tosses a ball upward on a stream of air. Assemble a basketball launcher and practice shooting hoops with air power. Make a fan-driven car that drives forward, propelled by a stream of air. Experiment to see how much weight your hovercraft can support.
A robot fit for the circus! With this kit, you can build a robot that walks, step by step, along a tightrope. How? Thanks to the robot’s main component, a gyroscope, it can maintain its balance and perform this fun trick without falling over! Through eight experiments, you can explore the astonishing powers of the motorized gyroscope and understand the physics behind its amazing behaviors. Experiment with getting the robot to walk on different surfaces: a tightrope, on a solid tabletop, on a soft surface, and even on your arm! You can also experiment with the balancing behavior of the motorized gyroscope by itself, testing its ability to balance on its edge, on your finger, on a pole, and dangling from a string.
The kit includes parts to build the robot and experimental setups, including a frame for the tightrope. By constructing the robot and performing the experiments with the motorized gyroscope unit, young engineers can learn about the science of gyroscopic devices and the indispensable role they play in our lives.

In one way or another, almost every form of energy we use originates as energy from the sun. Solar energy directly powers photovoltaic cells and thermal collectors. Indirectly, we get power from plants grown by the sun, oceans heated by the sun, and Earth's weather systems sustained by the sun. Even the energy stored in fossil fuels originated as energy from the sun, captured by plants and animals millions of years ago. Physics Solar Workshop explores the topic of solar energy, focusing on photovoltaic cells. By building 12 models and conducting 30 experiments, you will learn how solar cells transform light into electrical energy, and how motors and mechanical devices can optimize the work done by this energy. You will build different types of vehicles and machines to demonstrate how gears can convert and transform power for different needs. There are 320 parts, which are also compatible with the other kits in our Physics line. The 64-page book offers illustrated instructions for the projects. Developed with Greenpeace in Germany.
