A stinkpot or stink-pot was an incendiary and suffocating weapon used in the 19th century during the Qing Dynasty, especially in naval operations. It is an earthenware incendiary weapon part filled with sulphur, gunpowder, nails, and shot, while the other part was filled with noxious materials designed to emanate a highly unpleasant and suffocating smell to its enemies when ignited. British Admiral Sir William Robert Kennedy recorded the use of the stinkpot in 1856 during the Second Opium War in his book ''Hurrah for the Life of a Sailor - Fifty Years in the Royal Navy''. He described it as: Describing the method of use of the stinkpot, Kennedy writes: Stinkpots were used in the War of 1812 by the British Navy during a bombardment of Stonington, Connecticut on August 9th, 1814.

Pulley
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave. A pulley may have a groove or grooves between flanges around its circumference to locate the cable or belt. The drive element of a pulley system can be a rope, cable, belt, or chain. The earliest evidence of pulleys dates back to Ancient Egypt in the Twelfth Dynasty (1991-1802 BCE) and Mesopotamia in the early 2nd millennium BCE. In Roman Egypt, Hero of Alexandria (c. 10-70 CE) identified the pulley as one of six simple machines used to lift weights. Pulleys are assembled to form a block and tackle in order to provide mechanical advantage to apply large forces. Pulleys are ...
