Abstract
An educational toy kit that can be assembled into a simple device that translates changes in the volume of gas trapped in a rigid container with a flexible membrane into the movement of a graduated indicator. The changes in gas volume can be created by changes in ambient pressure, as in when changing altitude or temperature and thus can be used to observe the inherent relationship of a gas' volume to its temperature and pressure as governed by the Universal Gas Law (PV=nRT) for the purpose of education and entertainment.
Claims4
An educational toy, comprising:
- a container;
- a flexible membrane and means to attach it to the container;
- an indicator that is mechanically coupled to the flexible membrane in such a way that it moves in response to the movement of the membrane.
