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?

Aerogels are the world’s lightest (least dense) solids. They are also excellent thermal insulators and have been used in numerous Mars missions and the Stardust comet particle-return mission. The focus of this video is silica aerogels, though graphene aerogels are now technically the lightest. Continue reading
The approach is a response to growing anxiety about plastic pollution and is also an acknowledgment that household recycling has not kept pace with the rapid spread of cheap consumer packaging discarded after a single use Continue reading
