Gamvdout Physical Steam Pressure Piston Motion Model -Steam Engine Model - Physics Science Experiment Engine Model Educational Physics Experiment Kit,

HIGH QUALITY: Made of brushed less steel, the bottom plate is smooth, sturdy and durable, ixed by screws, all kinds of parts are rigorously connected, large and small flywheels, and teaching is more convenient. HOW IT WORKS: The steam engine uses the pressure difference as the power source to drive, to demonstrate the working principle of the steam engine. Use the gas pressure difference to push the piston to make the piston move up and down. WIDE APPLICATIONS: Perfect for Kids' science project, education toys, physical or mechanical learning, teacher's Demo props on the class, birthday gift for friends, families, kids, etc. EASY TO USE: Connect the air supply connector, turn on the air intake switch, and gently flip the flywheel by hand, and the machine can operate normally. After use, turn off the air source and turn off the air intake switch. SPECIFICATION:17.2 x 13.1 x 20.6 cm/6.7 x 5.1 x 8.1 inches(L x W x H).
