Liquid Crystal Temperature Strip

This fascinating temperature tool can measure the surface temperature of any object, including the human body.  Each of the 21 encapsulated liquid crystals is optically active within the specific one-degree Celsius range indicated in front of it on the strip.  As the strip is held against an object, the numeral temperature corresponds to that of the object, and the color shown indicates fractions of degrees for precise measurements.  Use the included string to fasten the strip around your forehead to measure your temperature in real-time during strenuous activity!  You can even glue it to an aquarium to monitor the temperature and keep fish and aquatic animals healthy, or test the temperature of beakers.
