This kit is an add-on to the Super Precision Gyroscope. The kit is a modular set of        twenty four components that complement and expand the number of experiments        that can be performed. They are compatible with components that are supplied with        the gyroscope and can be used together. One of the main features is to provide 2        axis gimbals for the gyroscope but many other experiments can be performed.         The gimbals make precession and nutational forces easy to demonstrate.        
       
     

Gimbals are a mechanical support that allows an object to move freely on a number of axes.  The most common type of gimbals allows a gyroscope freedom on two axes. The 3rd axis is the  gyroscopes own spin axis. 3 or more gimbals can be added but only really demonstrates how to  reduce gimbal-lock, hence are not as common as that is more niche demonstration.  Although gyroscopes commonly use gimbals, gimbals themselves have other uses, for example  gimbals driven with servo motors can be used to accuracy position cameras and stabilise the image  reducing or remove the shake and blurriness of the videos.

A typical demonstration of a gyroscope when using gimbals is to spin up the gyroscope, put the  gyroscope in the gimbals then set the gyroscope pointing in a certain direction. In a classroom  environment this maybe towards a doorway or an inanimate object. The demonstrator can then  walk around the room holding the gyroscope/gimbals, regardless which way the person walks the  gimbals will also continue to point the same way.  Another common demonstration is to place the gyroscope and gimbals on a table and allow someone  to gently push the gimbals. By pushing one gimbal the person will feel the resistance from the  gyroscope but also observe precession of the other gimbal.
