Miniaturization often presents significant advantages—take the TV version of Honey, I Shrunk the Kids, whose running time perfectly matches the average time between sour-gummy-worm cravings. Shrink some sports down to size with today's Groupon: for $15, you get one day of unlimited go-karts, bumper boats, and miniature golf at Malibu Grand Prix in Redwood City (a $29.99 value).
Lead-footed motorists and boatorists can experience the best of each with unlimited access to Malibu's high-performance go-karts and weaponized bumper boats. Zip around hairpin turns, pick up speed on straight-aways, and fly over banked curves with a passenger in tow aboard Malibu's safe and speedy four-wheeled chariots. Malibu's post-adolescent playpen also lets amphibious athletes take a competitive dip with friendly bumper boat battles. Each buoyant water skimmer is surrounded with bumpers to encourage planned crashes, and the vessel comes equipped with a mighty water cannon perfect for drenching enemies or spritzing overheated allies. After an afternoon of speed, slow down with the thoughtful, zen-like meditation that is miniature golf on the park’s whimsically appointed links.
