    Description

    The Original
    LUCKY DRINKING BIRD
    This novelty is a classic scientific wonder, using the properties of thermodynamics
    to keep it in constant bobbing motion
    Do you understand the complex relationship between chemistry and physics that makes this simple heat engine operate?
    It is a perpetual motion machine, but more
    evaporation
    temperature
    pressure
    low pressure causes liquid to rise
    weight of liquid causes a drop in the drinking bird's head
    tilted head causes reequillibration of pressure &the liquid to flow back down
    Not really a toy...made of glass. Dye stains and irritates eyes if is glass gets broken
