You probably know that voltaic batteries come in all kinds of shapes and sizes, from tiny button batteries to car batteries to huge industrial heavy-weights. They turn chemical energy into the electrical energy that people use to power clocks, toys, cell phones, medical devices, tablets, cars, satellites… and an LED! These batteries seem pretty complicated but you can make a real voltaic battery right in your kitchen. Grab the ice tray and start the electrons moving. Continue reading
We’ve already been told that everybody poops – but did you ever stop to consider why? It’s thanks to our heroic through-gut that humans don’t suffer the same fate as jellyfish and anemones, and every hero has an origin story… Hosted by: Olivia Gordon
Use science know-how to create a tasty vanilla treat!
The Roman emperor, Nero, is credited as the first person to have a type of ice cream made for his meals. Snow was used to freeze fruit drinks that he enjoyed so much. In 1310, Marco Polo helped out as did King Charles I of France in 1640. The French served it in Philadelphia in 1782 to honor a new country: the USA! Dolly Madison served it in the White House in 1813. In 1846, Nancy Johnson invented the hand-crank ice cream freezer. Ice cream cones were first seen in 1904 at the Louisiana Purchase Exposition (better known as the St. Louis World’s Fair). The rest, of course, is history. The secret to making ice cream is to lower the freezing point of ice so it can freeze the cream. How? The scientific secret is plain old salt! Here’s a simple recipe you can follow right at home to make your own ice cream. Who needs Nero?

The milk industry produces in excess of 840 million tons of products each year. Why do humans drink so much milk? And given that all mammals lactate, why do we favor certain types of milk over others? Continue reading
