The popsicle was invented by an eleven year old. Sure, the original name was Eppsicle and it took many years for Frank Epperson to receive his patent for "frozen ice on a stick" and his grandchildren to rename it, but kudos to kid power.
Twin popsicles were introduced during the Great Depression, long before and completely ignored by my friend Alice and me when we split the cherry-banana version on a daily basis. Alice would break the popsicle in two, pull the cherry pop towards her, leaving the banana side for me. Neither flavor tasted like the actual fruit, but the cherry pop would leave your mouth all magenta.
