Children learn best from exhibits involving lights and colors, which means you can either take them to a children's museum or let them rub their eyes too hard. Teach wee ones safely with today's Groupon: for $17, you get a visit for four to DuPage Children's Museum in Naperville (up to a $38 value).

In the bright and colorful environs of DuPage Children's Museum, kids of all ages explore three stories of exhibits that entertainingly delve into art, math, and science. A recently opened train exhibit, Trains - Get on board!, encourages aspiring conductors to send a model train hurtling down the track or board a pretend train in a foolhardy attempt to avoid doing chores. Kryptonian kids don capes before stepping into the AirWorks area’s hair-blowing wind tunnel, and the WaterWays section offers two splash-happy water areas. Three exhibits cater to young explorers aged up to 24 months old with colorful balls and constitutional-law casebooks. Museum admission also affords access to drop-in studio activities, with upcoming sessions on building hoop gliders, kites, and skyscraper-climbing magnet boots.

Though DuPage Children's Museum sometimes offers a discounted price, this Groupon still offers the best deal available.
