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.

A Difficult to Find T-Shirt
These T-Shirts are nice. A super difficult to find. The manufacturer calls it a mock-turtle neck (MTN). But the collar height is actually a bit shorter than the traditional MTN, which is great. It's closer to a regular T-Shirt that comes all the way to the neckline. And very somt a comfortable. This is the perfect style of T-Shirt to wear under a sportscoat, if desired. Or under a shirt where you want the T-Shirt to show for contrast. Just the right look.

Nice shirts for the price! But do not recommend for thick body types.
I bought 3 different ones. 2 Mediums and 1 2XL. The mediums fit correct and really nice! Would definitely recommend for the price! More like a exercise material, and sticks to your body shape... Sooo the 2Xl did not fit the person correct. Was so tight... And the strech is to stick to your body... So would not recommend for anyone a bit hefty or fit tbh. But the shirts are good materials and feel nice for a fresh day out or to use as gym clothes!!

Great Value heat gear material with high neck collar and loose fitting
Color: Black, Size: X-Large
My husband has been looking for mock neck shirts that are comparable to UA heat gear material but that are short sleeve and fit loose to wear under his work uniform. These seemed to have been a good soft quality option and the price is is great.
