The maximum size of a raindrop is typically around 5 millimeters in diameter. Raindrops larger than this size are rare because they become unstable and break apart due to air resistance as they fall through the atmosphere. However, under certain conditions such as in intense thunderstorms or tropical cyclones, raindrops can grow larger than 5 millimeters through a process called coalescence, where smaller droplets merge together to form larger ones. **

At the first coin-operated vending machine, which was created in the early 1880s by Percival Everett, customers could purchase postcards for their money. The machine was installed in the railway stations and post offices in London, and for a penny, customers could receive a postcard featuring a picture of the surrounding area. This early vending machine was a novelty at the time and provided customers with a convenient way to purchase postcards without the need for human interaction. **
