Unknown. In 1981, the German company, Trolli created Gummi Worms. "Gummi" means "rubber" in German.
How to Celebrate
To celebrate Gummi Worm Day, go eat some Gummi Worms. They are available in regular and sour flavors. If you want to make them extra special, make a dessert with them called "dirt".
Mmmm… one of my favorites!
To celebrate this day, we selected the 1970s Worms Cherry Cola Can. This is a white can showing the head of a smiling kid and a wooden sign with the words, "Best Worms You Ever Tasted". Below the sign it reads, "A specially blended, quality, carbonated soda with a taste so new and exciting that it required a name just as unusual as our soft drink." On the back of the can the kid and the sign appear again, but this time the sign reads, "I Like Worms".
Happy Gummi Worm Day (7/15)!
