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. Recommended for 8+.

Nice shirt but too short
I'm 6', 175 with a bit of a longer torso. That makes me a slim build bordering on tall/slim. The material seems on par with similar offerings from Nike and the shirt looks and fits quite well (I like the slim tailor) but it was not long enough to tuck in as a medium (right at my belt line). I tried a large which is getting a little big around and it was still too short. XL was ridiculously wide on me and still not long enough. Bottom line is that Amazon needs to offer this shirt in a slim/TALL with about 3" of additional length. There would be a whole lot of buyers. I'll have to continue to go to the specialty shops in search of MT and LT sizes.

Nice for the price
I am 6’4” and 195 lbs so I need a large size for most shirts. I need it for the length, but not the width, so shirts this size tend to bow out at the back and make me feel a bit like I am wearing a tent. I prefer polos made of a very thin, breathable and moisture wicking fabric. A decent looking shirt you can wear on hot and humid days without any undershirt and stay comfortable. Old Navy makes a fantastic version, very similar to the ridiculously priced Under Armor version, and I was hopeful that this Amazon version would compare. It does, but has a few drawbacks. If this sounds like you, keep reading. If not, thanks for getting this far. I’ll keep this brief with a list of pros and cons below. Suffice it to say, I like the polo enough not to return it, but it is still a step below some of the shirts produced by other outlets. Cons: 1. It is far from wrinkle free, though I’m not sure it is even touted to be. It does tell me, though, that this fabric won’t be as soft as I prefer. 2. The color is a little darker (I got the coral) than it seemed in the picture, but not terribly so. 3. The “slim fit” is what drew me in and while it better than most, the back still bows out a bit 4. The fabric is clearly moisture wicking, but not the light fluffy kind. I know I’m starting to sound like a snob, but if you know what I mean, you know what I mean. Sometimes a shirt feels heavy when you sweat in it. The idea of the moisture wicking fabric is to pull that sweat away as fast as you produce it to aid in the evaporative cooling taking place on your body. This shirt doesn’t feel heavy, but I’m not sure how long it will stay that way on a really hot and humid day. Pros: 1. Price. For $15, I can become blissfully ignorant to the cons listed above. 2. Fit. It isn’t perfect (Yes, I know this is listed as a con too), but if you have a tall, lanky body type like me, a large will fit you better than your average polo. After a trip or two through the dryer, probably even more so. 3. Convenience. Now that I know this is a good fit for me, I can try all the different colors I want from the comfort of wherever I choose to be with my phone.

2nd shirt purchased for golf team priced right slim fit comfortable
We needed golf shirts for being on the school golf team. Brand name golf clothing is extremely expensive and not worth it for a growing slim teen so our first purchase was this shirt in a different color. This is the 2nd shirt we've purchased after loving the first one. Good quality, value, and comfort. Easy wash and dry. Can be washed and thrown on a hanger to dry. No shrinkage. Perfect fit. This is a men's small that fits great on a person ~ 5' 10". The material is thin and does not hinder golf swings. Love that this shirt, and most Amazon clothing, has no brand markings. Wise marketing that Amazon's clothing is NOT labeled.

Great shirt & my son loved it.
Size: X-Large, Color: Blue
bought it for my son and he loved it. In fact when I called him he was wearing the shirt said it fit him well, it looked great. It was comfortable. He loved the quality & the cut. The length was great and ask me where I got it so I sent him the link so he could buy more in other colors. He loves to golf and said this is a perfect shirt for that. Plus the price was right.

sizing runs a bit big but very comfortable, i love these and ordered multiple colors
Size: X-Small, Color: Black
Initially, i ordered a small and an X small based on reviews here. Glad i did. I opened the x-small first and it fit perfectly. Returned the other one unopened. Sleeves fit my arms well. Collar stands up well. Shirt has sufficient length to tuck in too. Not super long though if you want to untuck with jeans. I'm 5'6 140#. I lift weights regularly and run. I'm right at 11.8-12.0% body fat. I typically wear a small in the amazon essentials slim fit t shirt. Those fit really well in size S. Check them out too if you have not yet. These polos XS fits equally well for my body type.
