The earliest known reference to a vending machine is in the work of Hero of Alexandria, an engineer and mathematician in first-century Roman Egypt. His machine accepted a coin and then dispensed holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened a valve which let some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counterweight snapped the lever up and turned off the valve.

Megan writes: "Our lockdown sanity walks now include a pair of googly eyes. I declined my sons' suggestions to stick them to a dead bird and a pile of dog vomit, but this was a triumph."
Best restaurant review
"I'd never eaten a fish in my life, but recently I went for a swim in the ocean and was bitten by a fish. I'm not sure what kind but it hurt. So I decided to get my revenge by eating its friends and family, harnessing the power of aquatic supremacy. I wasn't sure what type of fish was best but Stephanie did a really good job of explaining the species available for consumption. She even went into details describing the texture, aroma and flavour of each. She then helped me narrow down my options to the meal that was right for me and I loved every last bite. I got Cajun-style Catfish with zucchini and wedges. Thanks so much Stephanie, you really know your fish."
