Bubble gum is often dispensed in bubble gum machines that usually cost 25 cents.
Some chewing gums are hard to blow bubbles with. Most notably they are ones that only want to freshen your breath such as trident and chiclets.
There are several methods to blow bubbles. One method is to flatten the gum against the roof of your mouth then press it up against the back of your teeth. Next, you push it out a bit with your tongue then blow.
The first bubble gum formulation, Blibber-Blubber, was developed in 1906 by Frank Fleer. However, the gum was never marketed. In 1928, Walter Diemer, an employee of the Frank H. Fleer Company, improved the Blibber-Blubber formulation, resulting in the first commercially successful bubble gum, Double Bubble. Double Bubble's pink color set a tradition for nearly all bubble gums to follow.
During World War II, another gum manufacturer, The Topps Company, marketed a brand of bubblegum under the name Bazooka. Beginning in 1953, Topps added a small comic strip packaged with the gum featuring the character "Bazooka Joe".
