While strapping a fin to your back and pretending to be a shark may have been the way to scare your pool-going friends in the 20th century, it s time to upgrade that age-old gag. Why not try the remote controlled robotic shark from Hammacher Schlemmer? This mean monster from the murky depths is two feet long and can convincingly move like a real shark. There s a 40-foot range from the remote to the shark and the remote can even be taken underwater for even more fun. Like all good things there s a catch: the batteries only last for 15 minutes per one-hour charge. If you want, though, you can purchase an additional battery to ease the pain a little bit. This mini Jaws will set you back about $100 and comes in either blue or red, not to mention that it can operate on one of two frequencies, enabling complex wolf pack-style missions.
