TitleDrawing, Glass balls by Henry Oldenburg
Date26 November 1662
DescriptionDrawing of a double glass ball used by Robert Hooke to prove the compression of air in the internal glass ball. This was reported among other experiments using glass balls to the meeting of the Royal Society on 26 November 1662.

ABC shows a glass ball made of white glass melted in the flame of a lamp and sealed up while the ball was very hot. DFEIK indicates a bolt head cut off at IK to fit in the ball and sealed up with cement afterwards. Water is then poured in between the bolt head and the glass ball until it reaches H. When the top of the glass ball A is broken, the height of the water rises to G (1/8 of an inch), which indicates the measure of the air that was compressed in the glass ball ABC.

The original drawing by Hooke is at CLP/20/3/3.
