I found some great old fashioned candy on sale at concession at the musical Newsies. Since the show is loosely based on a true story about newspaper boys who went on strike in 1899, the concession stand sells "nostalgia" candy--flavors that parents remember from childhood. I did a few experiments, and also learned some new facts!
Come see amazing high school singers and dancers perform Newsies at Lake Washington High School in Kirkland, WA, this Friday and Saturday--and get your own nostalgia experiment candy!
Zotz arrived in the US in 1968 after being invented in Italy. The center fizzes when eaten, because a mix of baking soda and malic acid starts reacting to form bubbles in the presence of water (or saliva).
Cow Tales are produced by Goetze's Candy, which started making chewing gum in 1895. Fun fact about Cow Tales: though they look like most caramels, they contain flour, making them closer in substance to Tootsie Rolls.
Aftershock candy is based on Pop Rocks, which were invented in 1956 by a chemist hoping to trap enough bubbles inside candy to dissolve into carbonated soda. While he couldn't capture enough carbon dioxide to make soda, the trapped bubbles explode and escape nicely when added to water!
