You can create simple machines at home using waste materials like cardboard, plastic bottles, and bottle caps. For a lever, use a sturdy stick as the beam and a bottle cap as the fulcrum, placing weights on one end to see how it balances. For a pulley, thread a string through a plastic bottle top and attach it to a support, allowing you to lift small objects. Lastly, a inclined plane can be made by propping a piece of cardboard at an angle to roll a ball down, demonstrating the mechanics of simple machines.

William Painter, an American inventor, is credited with inventing the bottle cap in 1892. His invention revolutionized the bottling industry by providing a convenient and effective way to seal bottles. Bottle caps have since become a standard feature on most types of bottles.
The first modern bottle cap was a screw-on cap invented in 1856. There was also a recloseable wire-and-cap type of bottle cap invented in the same year, still used today on some high-end beers such as Grolsch. The modern "crown cap" bottle cap was invented in 1890, modernized to the "pilfer proof" cap in 1936, and twist-off bottle caps in 1966. Bottle caps are no longer manufactured today, as most people drink their beer straight from their high-speed internet connection. :)
