Questions & Answers
If the device has a slight spring constant of 30 U/s as low as you want, you will notice some stretching of the spring when a few ounces are applied. It causes heat to be introduced into the spring, which gives rise to spring constant that exceeds that of currents. In this case, the load will rise because the spring is heated. Removing the current has the effect of cooling and nsible for removing the spring will cool and the weight will fall. I was able to move the spring up and down smoothly after using a 3V supply for a short time at around 100-200mA. As quickly as the current is transmitted, springs move upward as long as only a short while until the spring cools, which takes a longer period of time in case the air is needed to cool them further. As well as taking a photo of the spring, you can also deform it any way as you wish, and the image will look like a destroyed spring, but the Spring will soon return to its original shape almost as soon as you place it in hot water. Machines can be created where a spring is filled with hot or cold water, together with an easy-to-use motor. Several of these machines are available at Youtube.
My wife used it for a toy lesson we used for our children. Taking the shape of a holy ghost and twisting it out to shape, apply an ice cream and shake it. As a result of fire or even really hot water baptism, the spring is restored to its original form. Kids will appreciate knowing that God will restore them no matter what they are up against.

Each spring measures about one-inch in length. Within a few hours, I was contacted by the seller, which was a five-piece process. I find it very deceptive to describe it this way.
The package consisted of 5 springs, but I came home with only one spring even though the package states on its packaging that there will be 5. It was not advertised as such. As a result of this misunderstanding, I am deeply disappointed with the seller and Amazon.
The performer is good for demonstration purposes. However, Nitinol by itself does not exhibit quite the level of force normally applied in space, which could contribute to some very interesting results.
This is a short review of this book. awesome! Thanks for sharing it! Sunday classes can be incorporated with it as object lessons.
The product works just fine.
