Product Details

Discovery Mindblown DIY Model Engine Kit offers a hands-on STEM learning experience for aspiring engineers. This 104-piece working model features a clear design that allows you to observe the inner workings of a 4-cylinder engine, including moving pistons, valves, and a spinning fan. The kit includes LED spark plugs and realistic sound effects to simulate a real internal combustion engine. It comes partially assembled with the original box and battery pack, making it a great educational project for kids aged 8 and up.

Daily Cleaning: Use a soft brush or damp cloth to gently wipe away dirt. Avoid harsh chemicals. For mesh areas, use diluted mild detergent and a soft brush.

Drying: Air dry in a cool, shaded place after cleaning. Avoid direct sunlight or high heat, which can cause fading and glue deterioration.

Storage: Stuff with paper to maintain shape when not in use. Store in a dry, ventilated area to prevent mold. Rotate between multiple pairs to extend lifespan.

Usage Notes: Designed for basketball. Not recommended for hiking, long-distance running, or other specialized sports where different performance features are required.
