Humidifier Experiment
This Humidifier Experiment uses the principle of ultrasonic high-frequency oscillation to make the water in the humidifier vibrate with ultrasonic high-frequency for 2 million times per second to atomize into 1 micron to 5 micron ultrafine particles and negative oxygen ions, and then diffuses the water mist into the air to achieve uniform humidification, which can clean the air.

Air Powered Car Experiment
The Air Powered Car Experiment pushes the piston backward by compressed air, and the piston rod drives the rack and gear to rotate, so that the car can move forward rapidly. The principle and application of increasing air density to convert gas pressure energy into kinetic energy are studied through experiments.

Diy Steam Engine
Diy Steam Engine uses alcohol lamp to heat the water in the closed space. When the water is heated and vaporized into water vapor, the volume expands at the same time, generating air pressure to push the piston to move, generating mechanical energy, giving the flywheel an initial speed, pushing the piston to move back and forth, and driving the motor to generate electricity through gears. Understand the basic principle and application of steam engine through experiments.

Electric Bell Experiment
Electric Bell Experiment uses the magnetism produced when the electromagnetic current passes through to draw the shrapnel under the small hammer to strike the bell. At the same time, the circuit is disconnected, the electromagnet loses its magnetism, the small hammer is bounced back again, the circuit is closed and repeated, and then a continuous hitting sound is produced. Understand the working principle and application of electromagnet through experiment.
