Stirling Engine Tank Kit External Engine Model Physical Experiment Engine

Features:

 
.The appearance is exquisite and simple, the unique tank shape, the decorative gun makes the tank model more realistic, the core components are made of aluminum alloy, durable and not easy to rust, the track is made of rubber, which makes the overall structure light.

.The tank has an alcohol lamp fixing bracket, which is safer and more reliable. The lightweight fuselage structure and sufficient power make the tank have a certain ability to cross obstacles.

.Instructions for Use: Put the tank engine model in a horizontal position, inject high-concentration alcohol into the alcohol lamp to ensure the safety, and ignite the alcohol lamp. Preheating for 1 to 2 minutes, the alcohol lamp heats the piston tube, and the dry air expands to generate power. At the same time, the flywheel is assisted by hand to drive the flywheel to rotate rapidly, and the tank will start moving forward.

.Tip: 95% alcohol (Not Included), you can't add water, kerosene, gasoline, lighter oil, beer, etc.

.Education and fun, through the hands-on operation, you can observe the entire Stirling engine running process, more intuitive understanding of the Stirling principle, and deepen your interest in physics.

.Not only is it an excellent educational toy for children, but it can also be used as a collectible.

.The product is suitable for people over 14 years old.

.Tips: Be careful not to be burnt by high temperature during the operation.

Post-COVID Sock Hunt: Finally a Win
Size: Medium, Color: (001) Black / Black / White
Ever since COVID, I haven’t been able to find a pair of socks that hold up for more than a few months. Brands like UA, Adidas, and others seem to have cut corners—likely in response to inflation—by downgrading materials and labor rather than raising prices. The result? Socks that wear thin, rip easily, or lose shape fast. These, however, have been a pleasant surprise. I’ve been wearing them for a few weeks and so far, they’re holding strong. You can tell some cost-saving measures were still made—certain areas feel slightly thinner—but overall, the construction is solid. A key win: they stay on. These are ankle socks (not “no-shows”), and they hug the ankle securely. That’s a huge plus in a world where most post-COVID no-shows slide off halfway through the day. We may never get back to the pre-COVID quality standards without paying a premium, but for now, these are a reliable choice. Ratings: • No slipping: 10/10 • Price: 7/10 • Durability (so far): No pilling or loose threads — promising start.

Great Quality and Stylish
Size: Large, Color: (001) Black / Black / White
Exactly what I was looking for. I don’t like socks that are no-show that your ankles rub on the shoe. These are taller than that but shorter than socks that go up and over the ankle. They’re comfortable, good quality, and pretty thick. They’re form fitting m, but not compression. I dint like compression socks, and these are tight, but not too tight.
