Did you know vegetables high in minerals like iron, magnesium, and selenium—specifically carrots, kale, spinach, green beans, and bell peppers—can spark (or "arc") in a microwave ? (These minerals act like metal, causing electromagnetic waves to bounce off them. Denser veggies, including potatoes, may also spark.)

Did you know the glossy, shiny coating on jelly beans is primarily made of shellac (also known as confectioner's glaze), which is a resin secreted by the female lac bug (Laccifer lacca) ? (This natural, edible wax, often combined with carnauba wax or beeswax, is applied to give the candy a hard, polished finish.)

Did you know the giant golden-crowned flying fox is the world's largest bat, weighing up to 3.5 lbs with a wingspan of 5.5 to 6 feet and the tiniest bat is the Kitti's hog-nosed bat (or bumblebee bat), weighing about 0.07 oz with a 6-inch wingspan ?

Did you know wheelbarrows were invented in ancient China, with the earliest evidence, like tomb carvings, dating to the Han Dynasty around 100-118 AD, used for military transport, though some historians suggest earlier Greek construction use around 400 BC ? (They appeared in Europe much later, around the 12th-13th centuries. Chinese designs featured a large, central wheel, while European versions later moved the wheel to the front.)

Did you know Charles Dickens, an avid cat lover, famously had the paw of his beloved pet cat, Bob, turned into a letter opener/paper knife after the cat died in 1862 ? (The memento, engraved with "C.D., In memory of Bob, 1862," was mounted on an ivory blade and is currently housed in the Berg Collection at the New York Public Library.)
