5 Tech Gifts for the Alpha Geeks in Your Office
5. Air Swimmers, $40
Available in the Flying Shark or Clown Fish version, these blow-up dirigibles can be used to scare the accounting folks or perform reconnaissance in the cafeteria. They have to be assembled by adding fins and adding your own helium (you can buy canisters online or bring the Air Swimmer to any store that fills party balloons). The balloon is made of nylon and comes with a radio controller.
