Leonardo da Vinci discovered that images reflected in mirrors are reversed, a phenomenon that can turn mirror-gazing butterflies back into a flightless glob of butter. Harness the powers of reflection with today's Groupon: for $8, you get two admissions to the Amazing Mirror Maze in Bloomington (up to a $17.54 value). Children under five are admitted for free.

Cradled within the colossal confines of the Mall of America, the Amazing Mirror Maze boasts 2,500 square feet of twisting turns and seemingly infinite hallways. Instead of navigating a garden maze swarming with buzzing bees, unruly sprinklers, and riddling lawnmowers, savor the thrill of skipping through a gleaming web of mirrors. Archways emblazoned with technicolored diamond patterns transport mazers into a commodious kaleidoscope abounding with vibrant shapes and colors. Negotiate the reflective labyrinth amid a myriad of identical twins, each one of them vying for the single scrap of muenster cheese at the end of the hallway. The Amazing Maze offers a safer setting to get lost in than a knife throwers convention.

Though the Amazing Mirror Maze sometimes features a discounted price online, this Groupon still offers the best deal available.
