If you grew up in the past century (1900 - 1999), you probably encountered gum balls at a store or friend who had a gumball machine. Do they still exist? I can’t say I’ve seen one in a store for quite awhile, but you can still buy them. The vending machine businesses have gone to mostly electronic machines, which means they can take credit cards and serve more items. Sadly this doesn’t leave much room for the old standard gum ball machines.
