Hydraulic Excavator

The principle of operation is hydraulically . Liquid transmission is a form of transmission that uses liquid as theworking medium for energy transfer and control.Power is transmittedby pressing the liquid in the syringe to raise and lower the robotic arm.
It's an application of Pascal's Law:An incompressible stationary fluid atany point in which a pressure increase is generated by an externaforce, and this pressure increase is instantaneously transferred to allpoints in the fluid.

Aerodynamic Airplane

The principle of operation is aerodynamic airplan . Aircraft propellers rotate at high speeds driven by engines andcreates a tensile force that pulls the airplane forward.There willbe two forces at the same time
One is the aerodynamic force that pulls the fan blade forwardand the other is the reaction force created by pushing the airbackward after having the fan blade twisted.

Floating Ball

The principle of operation is air compression reflux . Place the foam ball above the air stream, the air currents arepounding the ball, keeping it from falling, when the ball arejumping out of the airflow, the air around it pushes it back into theairflow, Because the surrounding air velocity is small and thepressure is high, while the air in the stream has a high velocity anda low pressure, this is the "Bernoulli effect".

Bubble Maker

The principle of operation is air squeezing . The movement of a bubble machine is made up of a water pumpand fan parts, the water pump part will bubble water pumped tothe air outlet, and then the fan will produce wind to blow thebubble water outward.
In the process of blowing out the air will be sucked into the liquiddroplets, so that the liquid droplets will expand, and the bubblewater will turn into gorgeous colorful bubbles.

Water Dispenser

The principle of operation is negative pressure for water circulation . The water dispenser relies on the pressure of the air, the internawater circulation, and the water is dispensed through negativepressure. Water pump through the water pressure to control thecircuit of a small electric appliance, the fixed volume of theinternal air compression,the formation of negative pressureunder the action of the pressure difference, it can be sucked upand pressurized to the pump outlet.

Hydraulic Lifting Platform

The principle of operation is pascal's principle.The working principle of hydraulic lifting platform is based on Pascal's principle, which meansthat when liquid is under pressure in a closed container, when under pressure, it will generateequal but opposite reaction forces. in hydraulic lifting platforms, this principle is used to raiseand lower.

Paddle Steamer

The principle of operation is transforming mechanical force into propulsion.Paddle Steamer is a type of ship equipped with wheels on both sides. Because a portion of thewheels is exposed above the water surface, The paddlewheel is a partially submerged propulsion device, resembling a wheel in shape. When thepaddle wheel operates, its paddles push water backward, and the wheel itself experiences areactive force from the water, This reactive force hull propelling the ship forward.
