Top off onboard meals with the favorite dessert of summer: ice cream. Industrial Revolution's Play & Freeze Ice Cream Maker gives families a new after-meal treat and activity to enjoy while boating. The Play & Freeze is a soccer ball-shaped container made of durable, lightweight polycarbonate. All you have to do is pour in the ingredients and shake, rattle and roll the ball for 15 to 20 minutes. Families can pass the time by shaking the ball in a game or sing-a-long until the ice cream is ready. The Play & Freeze makes about a pint of ice cream and retails for $29.95. (888) 297-6062.
