The vacuum engine, also known as the Flame-Licker Engine or Flame Eater, is a simple yet magical machine that demonstrates the conversion of heat into mechanical motion. With its adjustable speed feature, the engine can be run at a slower pace, allowing users to fully understand the operation of the beam when running slowly. The engine's low maintenance and reliability, thanks to its fewer moving parts, make it a user-friendly option for mechanical beginners.

Crafted with high-quality stainless steel, brass, and aluminum alloy materials, the engine boasts a durable and well-made construction. The acrylic base provides a stable and easy-to-use platform for the engine's operation. This mechanical artwork not only offers visual texture and an aesthetic appearance but also delivers impressive performance, making it an excellent gift for mechanical enthusiasts.

Included in the package are the vacuum engine, 3 valve slices, 1 wick, 2 hex wrenches, and instructions, providing everything needed to set up and enjoy this captivating mechanical device.
