.The cylinder is processed by high-precision lathe, which adds more heat sinks, beautiful appearance, better heat dissipation effect for a long time and longer life.
.The connecting rod is made of high quality 304 stainless steel, which adds a through hole, which makes the engine more stable and quiet under high speed operation.
.The Stirling engine is powered by the expansion of the gas and the compression of the cold. 95% alcohol (self-prepared) should be used in the operation. Water, kerosene, gasoline, lighter oil, and liquor should not be added.
.Place the engine model in a horizontal position, take out the alcohol lamp, add about 2/3 of the alcohol to the alcohol lamp, and ensure that the alcohol lamp is ignited under the premise of safety, you can use the hand to gently assist the flywheel to turn the engine to start the engine
.By personally operating, you can gain a more intuitive understanding of the Stirling engine principle and deepen your interest in physics by observing the entire engine's operating flow.

Great for me
Color: 03 - Tinted (1.7 oz)
I’ve tried a lot of face sunscreens over the years, and EltaMD UV Daily really stands out. It feels incredibly lightweight and absorbs quickly without leaving any white cast, which is a must for me. I love that it layers well under makeup and doesn’t pill or feel greasy throughout the day. What makes it a staple in my routine is how it keeps my skin hydrated while still offering solid sun protection—it almost feels like a moisturizer with SPF. My skin is on the sensitive side, and this one hasn’t caused any irritation or breakouts. It’s one of those products I actually enjoy using every day, which says a lot. Definitely a 5-star go-to for me!

Amazing
Color: 02 - Daily Hydration+ (1.7 oz)
The best sunscreen I have used. I am prone to breakouts and using this daily hasn’t caused any flares. I also wear makeup daily and it sits well on top of the sunscreen doesn’t get overly oily throughout the day. Doesn’t have an overwhelming typical sunscreen smell. Feels nice on skin doesn’t feel sticky or gross like many other sunscreens. Pricey but an amazing investment for your skin!

Best tinted SPF, problems with pump
Color: 03 - Tinted (1.7 oz), Color: 03 - Tinted (1.7 oz)
This is my favorite tinted moisturizer. It is very lightweight and perfect for daily wear. Provides just the right amount of coverage while also protecting from sun damage. My only complaint is the pump. The bottle is full of product, but as you can see in the video, nothing is coming out. I’ve been buying this brand for years and have never had a problem, so not sure if it’s the change in packaging or I just got a defective pump.
