Water Cannon to annoy pool users

How would you like to annoy your friends in the pool with squirts of water without getting wet yourself? Perhaps this remote controlled Water Cannon could help. This toy can be controlled to move forward, backward, or turn its turret 360 degrees and up and down via a simple radio controller. I assume the remote control itself is waterproof so that you can launch attacks on friends who are on land, but if it isn’t, you can be on land and basically be a pest in the pool itself. The Water Cannon is capable of shooting bursts of water up to 10 feet in length, which is pretty impressive. Powered by four AA batteries, the Water Cannon retails for $129.
