The brass ball will just pass through a brass ring when cold, but when the ball is heated in boiling water it expands so that it no longer passes through the ring. The ball and ring demonstration of heat expansion has been in use since the early...

The spherometer was used to measure the curvature of lenses. Physical Description: In mahogany case with sliding lid. Calibrated brass disk on three legs.
Electric discharges; Scientific apparatus and instruments
When connected to a power source, a bright electric spark would flash between the two ends of the two outer posts. The middle glass post is made of photo gray glass (yellow tinted glass), which would have glowed. This instrument is visible in early...

This instrument allowed water to be heated to a temperature higher than boiling point at atmospheric pressure, resulting in considerably high pressure inside. Papin designed a model of a digester in 1680 that allowed a piston inside a cylinder to...
