Ice is nothing more than water that won't let people swim in it. Such stubbornness deserves comeuppance in the form of sharp metallic blades that merrily criss-cross to and fro across the frozen surface. Get your icy revenge with today's Groupon: for $8 you get two general admissions and two skate rentals at the Kent State University Ice Arena (a $17 value).

Home to the Kent State hockey program, the University ice rink is also open to the general public for two-hour open skate sessions on most days of the week. Parents can tow their tots, teenagers, or fiscally obligated adult children to let loose family-style at monthly themed-skating events, such as the crazy hair day (January 21st), 80's party day (February 18th), or luau skate (April 8th). Or, use today's deal in time to participate in the district-wide Kent City Schools challenge. Through February 2011, arena staffers will keep track of the number of student visits from each elementary and middle school within the Kent City School District, and will reward the school with the highest attendance rate with a two-hour skating party that includes free pizza, soda, and musical entertainment provided by a DJ. Open hours for public skate vary, but begin as early as 11 a.m., with nighttime winter skates lasting as late as midnight.
