\"tea-bags\"<\/a>The Truth About the Surprisingly Recent Invention of the Tea Bag, and the Women Who Really Invented It<\/a><\/p>\n

Legend says that brewing tea dates back to around 2737 BC, when tea leaves fell into water being boiled for Emperor Shennong of China. There does not appear to be any hard evidence of tea being discovered this way, but evidence we do have suggests that brewing tea did indeed likely start in China, first as part of a medicinal elixir. The first documented reference to this is found during the Shang Dynasty (1600 BC to 1046 BC). By the Qin Dynasty in the third century BC, it had become a relatively popular drink using just the tea (camellia sinensis), rather than mixed with other things as seems to have been common when used medicinally. From the beginning until the early 20th century… (more<\/a>)<\/p>\n

\"tar-and-feather\"<\/a>What Happens To A Person When They are Tarred and Feathered<\/a><\/p>\n

In times gone by, tarring and feathering was a go-to method used by mobs to punish or otherwise humiliate criminals or people believed to have wronged the community in some way. While it\u2019s mostly recognised as being a punishment handed down in colonial times, the history of tarring and feathering stretches back all the way to the crusades and possibly further, with the earliest known recorded reference to the punishment being an edict passed down by Richard the Lionheart in 1189… (more<\/a>)<\/p>\n

\"tongue-cow\"<\/a>What Causes Aftertaste<\/a><\/p>\n

Ever wonder why certain foods seem to have a weird flavor that hangs around after you swallow them? Aftertaste is generally classified as any taste that remains in your mouth after your food or drink has been swallowed or spit out. The exact mechanism that causes these sensations isn\u2019t fully understood. In fact, understanding how our brains perceive specifics tastes is still a subject of debate. The current leading theory of taste is that it\u2019s the perceived combination of several different sensory systems that include smell, flavor and what has been referred to as somatosensation- basically meaning… (more<\/a>)<\/p>\n

\"chalk\"<\/a>Blackboard Chalk Isn\u2019t Chalk<\/a><\/p>\n

Ubiquitous in many classrooms since the 19th century, chalk and chalkboards are familiar to most of us. White, powdery and prone to sticking to those surfaces where it is put (and just as easy to wipe away), chalk and its accompanying board are excellent instructional aids. Notably, however, most chalk today isn\u2019t technically chalk at all, but gypsum. Chalk and gypsum have both been mined since ancient times. Chalk (calcium carbonate) has been found in cave paintings that date back to 40,000 BC, while… (more<\/a>)<\/p>\n
