I met Sandy Stein at a Clippers game. As we chatted, she reached into her bag and took out her pretty and portable FANtastic pop-up fan. It was love at first breeze. The fan collapses into a pouch for the beach, a plane, an NBA game—you name it. Sandy's invention is a cool way to stay cool. ($5; isntthisclever.com)
