Nitinol Shape Memory Alloy Heat Engine Physical Experiments Toys


Features:


.Engine Principle: The shape memory alloy boasts memory after heat treatment, which changes the shape through the temperature difference of the phase transformation point. The nickel-titanium wire is straightened. When the temperature is high, it will be straightened, on the contrary, the temperature is soft. A constant cycle between the two temperatures will make the engine work.
.Mechanical Knowledge: Observe the whole working process of the engine to brief on its structure&principle and feel the magic process of energy transformation. Meanwhile, the engine is inducive to hands-on ability, learning interest and creativity.
.How to Use: 1. Install the flywheels on both sides of the crank mechanism in the engine package. 2. Put the nickel-titanium wire on the two flywheels. 3. Prepare a cup of 70°C hot water, put the small end of the engine in warm water and turn the flywheel to give its initial speed, so that the engine begins running. And it will decelerate to stop when it leaves the water.
.Notes: Pay attention to being scalded by hot water when playing. The diameter of nickel-titanium alloy wire is 0.49mm, which is dangerous. Children should use it under the guidance and help of adults.
.Superb Gift: The astounding mechanical craft, as a talking point that is packed with an elegant graphic carton for beauty&high value, is perfect for children and technology lovers being a creative and impressive gift for friends, families, teachers and students on birthdays and Christmas.

Consumer Reports gives this sunscreen one of their highest ratings and that was good enough for me. Goes on nicely.

Perfect for sensitive skin
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
I love this sunscreen. This was my first time buying after always using another company but recently my skin has started breaking out after using my old sunscreen. This sunscreen not only protects my skin but also does not give me a rash or irritate my skin.

This stuff WORKS.
Style: SPF 50 Lotion, Size: 6 Ounce (Pack of 1)
I am pale, I have rosacea, and I live in the south. That is a terrible combination. But this sunscreen has saved my butt (well, actually it’s saved my face). It doesn’t sting at, and when I accidentally got it into my mouth it didn’t leave a weird aftertaste (I smear it over my lips). This is my first mineral sunscreen, so I can only compare it to chemical sunscreens. But so far I think it lasts longer (and holds up to sweat better) than any other sunscreen I’ve used. It even survived a day at the water park with minimal reapplication. Now I will be honest, it leaves a white cast. But I don’t even bother trying to rub it all the way in. I just go out looking like Casper the Friendly Ghost. (Also it scored well on consumer reports, but the baby version scored even better, so I think I’ll try that next)
