Fuel Cell X7
Hydrogen Powered Car
The Fuel Cell Car & Experiment Kit (also sold on this website) has been a hot item since its introduction six years ago. It has captivated tens of thousands of children and adults alike, who have played and learned with it. Now, another version of the fuel cell car kit, the Fuel Cell X7, is available. This kit still has the Thames and Kosmos award-winning model car with its unique reversible fuel cell not found in other fuel cell car models. The car still functions in the same manner as the original Fuel Cell Car.
The Fuel Cell X7 edition is designed to be accessible to more users, both in terms of content and price. The manual focuses more on building and designing a fuel cell car, rather than the comprehensive lesson on the science of fuel cells and solar cells found in the original version. The minimum age is lower and the instructions are geared toward a younger audience. The kit has been optimized for simplicity and ease of use over thorough experimentation. With its new focus, some parts have become unnecessary and have been removed to reduce the cost. The kit that is right for you or your child will depend on your needs, interest level, and age group.
The full-color, 16-page manual contains easy, step-by-step instructions for assembling and using the car, as well as scientific explanations.
Ages 10 and up.
Features
- assemble a working fuel cell car
- discover how fuel cells work
- use a unique reversible fuel cell
- learn about the potential alternative energies for automobiles
- learn about fuel cell car design
Physics Solar Workshop
Solar Power Technology in Action
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.
Ages 8 and up.

Physics Discovery
Introduction to Mechanical Physics
With Physics Discovery, you will build 12 models and then conduct experiments with the models to learn about forces and simple machines. Each model demonstrates a fundamental idea in mechanical physics. For example, you can build a balance scale to learn about lever arms, a freight elevator to learn about pulleys, a bicycle to learn about wheels, a motion picture machine to learn about centripetal and centrifugal forces, and a transmission to learn about gears. Physics Discovery is a smaller, introductory companion to the best-selling Physics Workshop kit. It contains different building projects and experiments, and uses parts that are compatible with all of the kits in the Physics line.
The 32-page book offers illustrated instructions for building projects and experiments.
Ages 8 and up.
Features
- build a motor, force meter, catapult, balance scale, freight elevator, inclined planes, bicycle, transmission, motion picture machine, water wheel powered crane, dragster and sail car

Physics Workshop
The Science of Matter and Energy
Almost everyone has heard of a chemistry set. But until this kit was introduced, a physics set was almost unheard of. Physics is an essential science for everyone, and this kit provides a comprehensive explanation of mechanical physics. Through building 36 models and conducting subsequent experiments with the models, you will learn the fundamental laws of mechanical physics. Start by building small models, such as a fixed pulley, to learn about basic forces and simple machines. Then, work your way up to more complex machines, such as a pendulum clock, to learn more advanced concepts like work and centripetal force. This hands-on approach is both fun and effective because the principles of physics are demonstrated right in front of you. This kit includes more than 300 building pieces. The 64-page, full-color manual presents assembly instructions, experiments and explanations in a richly-illustrated, easy-to-follow manner.
Ages 8 and up.
Features
- build a windmill, two-speed crane, force scale, sail car, mars robot, hammer machine, centrifuge, pinball game, centrifugal switch, ship's lantern, and dozens of other models
