Get Your Science On: Nifty Nitinol
Check out this nifty experiment: nitinol is a nickel-titanium metal alloy with a remarkable property: shape memory! You can bend a nitinol wire with ease, but when it's warmed with a hair dryer it regains its original shape! How to Build It Nitinol, sometimes sold as Memory Wire, is widel

Nitinol Wire/Shape Memory Alloy - How to Use it
Nitinol wire, how to program this shape memory wire and test it. I use a candle flame for programming it and both a candle flame and electrical current for testing the nitinol. I also make a spring out of the nitinol wire and measure the force produced while it takes on its programmed shap

This is a special wire called Nitinol memory wire. It's an alloy that "remembers" it's original shape. You can set almost any shape that you want by using an extreme source of heat. After the wire cools, you can bend the wire into any shape but when you heat it, it will return to the origi

Fuming Nitric Acid vs. Lab Gloves
Fuming nitric acid is defined as having a concentration of HNO3 greater than 86%. This is much higher than the conventional 68% of common lab nitric acid. The reaction between the nitric acid and the nitrile and latex gloves is extremely exothermic and violent. It is often recommended to
