I was scouting around for interesting businesses, and stumbled across this article about an unusual kid's business, from a newspaper from 1952!
(From the Sarasota Herald-Tribune, June 30, 1952.)
Here's the text...
Nine-year-old Russel Green holds up a placard which advertises his unusual business - selling last winter's snowballs in the midst of this summer's heat wave. The ingenious lad stowed away a number of snowballs in his mother's deep freeze unit. His customers show typical reaction to the novelty. The little girl takes a bite out of hers, but the little boy at right thinks it would be more fun to throw it at someone. Russel finds business flourishing outside his Levittown, N.Y., home.
He's not getting rich at 15 cents a snowball - but I bet he and all the neighborhood kids had a lot of fun!
There may be some twists on this idea... apart from storing snowballs from the winter in your freezer, maybe you could manufacture
snowballs in the summer-time? Perhaps start a snowball-throwing summer-time birthday party business?
