Open up the everyday

Look inside a familiar device, trace what moves, and connect the working parts to the science.

Machines & MotionCar differentials and transmissions

How do driven wheels take different paths around a corner?

Follow a transparent car around a bend, open its rear axle, and discover how a differential shares motion, torque and a low-grip limit.

Electricity & EnergyBatteries and charging

What happens when you charge your phone?

Look through a phone, separate a battery’s layers, and trace two different journeys. One happens inside the cell. The other powers the world outside.

Everyday TechnologyMicrowave ovens and heating

Why is one bite hot while the next is cold?

See through a closed microwave, follow a bite around the turntable, and compare where energy arrives with where heat spreads afterward.

Machines & MotionFour-stroke engines

How does a piston turn fuel into motion?

Open a detailed engine, turn its crank, and take the assembly apart. Follow four different jobs hidden inside two very similar-looking turns.

Machines & MotionElectric motors

How does electricity make a motor spin?

Power a motor. Reverse its direction. Add a load and watch speed, current and turning force find a new balance.

Everyday TechnologyRefrigerators and heat pumps

How does a fridge move heat out of a cold space?

Look through a cold room and follow its refrigerant loop. Count the heat removed and the work added, then try putting both sides in the same room.

Machines & MotionGears and gear ratios

How do gears trade speed for turning force?

Turn once. Count what happens. Discover gear ratios, real-world uses, and why different jobs need different gears.
