Locomotive design, sectional, the valve and piston mechanism clearly visible through a glass plate with forward and reverse motions, demonstrates working with an air blower or even with mouth blowing.
Features
Locomotive Design: The model is designed to resemble a locomotive-style steam engine. Sectional View: It features a cross-section cut of the internal mechanism. Transparent Plate: A clear plate covers the mechanism, allowing for visible observation of the piston and valve movement during operation. Demonstration Method: The model can be operated using an air blower or even by blowing into it, to demonstrate the motion of the piston and the function of the valve mechanism. Forward and Reverse Motion: The model is capable of demonstrating both forward and reverse motions. Educational Purpose: It is specifically intended for use as scientific lab equipment for teaching mechanics and the physics of steam power.
