How are gumballs made?
Cylinders of flavored or unflavored gum are run
through a machine that forms balls. The gumballs are stored at 55-60 grades F
for many hours, until they become hard. Then they are places in a kettles and
coated with a flavored and colored solution of sucrose. The balls are tossed in
a machine for hours. Next, hot air dries the balls and they rolled in beeswax
or another kind of wax. The wax makes gumballs shiny and water-repellent. Now
they are ready to be dispensed from a gumball machine!
