3. Why is ice cream sold in a waffle cone?
At the end of the 19th century, ice cream was sold in “penny lick ice cream glasses.” They were rinsed with water, at best, before another customer used them.
However, a simple solution appeared in 1904. Due to the extremely hot weather, people crowded to buy ice cream, but the seller didn’t have enough glasses for all of them. A waffle booth was empty. The waffle seller quickly rolled one of his waffles into the shape of a cone and gave it to the ice cream vendor.
Everyone was happy with the result, especially doctors since the penny lick glasses were a reason for the spread of tuberculosis.
