Stirling Car Engine Model Miniature External Combustion Power Exquisite Physics Science Kit for Expe

Feature: 1. The engine model creatively combines the Stirling engine model with the toy car, powered by the Stirling engine model, driving a simple toy car to walk, with a variety of ways to play, full of fun. 2. The toy model itself has been assembled and can be used directly. Its excellent quality and exquisite appearance also make it have a high collection value and can be used as a high‑end gift. 3. The model owns exquisite appearance, the shape of the car is vivid, beautiful and textured, the polishing is meticulous, the color is bright, it is not easy to rust and discolor, and has a high‑end texture. 4. By operating the engine, children will observe and understand the process, and more intuitively understand the working principle of the engine, thereby deepening their interest in physics. 5. The model kit has a very wide range of applications, gifts for children\'s science projects, physics/mechanical learning, teacher demonstration props in the classroom, to friends, family, parents, children, etc. Specification: Item Type: Stirling Car Engine Model Material: Zinc Alloy Size: Approx. 15.8 x 11.4 x 9.5cm / 6.2 x 4.5 x 3.7in(Product size is manually measured, it is only for reference.) Purpose: Through Manual , You Can Observe the Entire Running Process of the Stirling Engine, Understand the Stirling Principle More Intuitively, and Broaden Your Interest in Learning Physics. Instructions Before Use： 1. Purchase Alcohol with a Concentration of 95%. the Alcohol with a Concentration Lower Than 95% Has a Low Combustion Value, Which May Cause the Engine to Fail to Operate Normally 2. Add About Two‑thirds of the Alcohol in the Alcohol Lamp (cannot Be Topped Up, It Will Overflow when It is Topped Up) 3. Then Ignite the Alcohol Lamp to Preheat the Heating Cylinder, About 2 Minutes, After the Preheating Time is Almost the Front End of the Trolley Shall Prevail; Turn the Flywheel Clockwise to Give the Engine an Initial Power, Otherwise the Engine Will Not Run (turn the Flame Larger and when You Turn the Flywheel a Little Harder, the Engine is Easy to Start) Package List: 1 x Stirling Car Engine Model 1 x Alcohol Lamp 1 x Blue Alcohol Lid 1 x Alcohol Cotton 1 x Screwdriver 1 x Wrench 1 x Tweezers 1 x Elastic Rope 1 x User Manual Note: Product size is manually measured, it is only for reference.
