Graeme's Water Pistol has arrived!
Packing a gun this well-designed almost feels like cheating. The secret of this weapon is an electrical motor that does all the work: Pull the trigger and it continuously fires a powerful stream until its generous 47-ounce tank has been emptied. Its 33-foot, sniper-like reach was the second strongest we measured, and you're guaranteed well over 100 rounds from a full magazine.
Its only flaw is that once the rechargeable battery pack is drained, you're a sitting duck. But the battery will last at least three full reloads and is easily replenished (charger included), so you can fight another day. Enemies may attempt to exploit the gun's weakness by dousing its electronics — say, with a water-balloon attack — but a couple of strips of electrical tape around the battery hatch will make the Tarantula impervious to such plots. Its overdone space-age styling may seem a tad embarrassing, but its performance on the battlefield will teach your enemies to show some respect.
