Aaron “Bunny” Lapin, who put whipped cream in a spray can a half-century ago and called it Reddi-Wip, died Saturday of heart failure. He was 85. Reddi-Wip was first sold in 1948 by St. Louis milkmen, and sales quickly expanded throughout North America. Lapin was soon dubbed the Whipped Cream King, and last year TIME Magazine listed Reddi-Wip as one of the century’s 100 great things for consumers, along with the pop-top can and Spam. Lapin is survived by two children, two brothers, a granddaughter and Touch ‘n Foam, a home-insulating spray product he also invented.
