   <dim:field mdschema="dc" element="description" qualifier="abstract" lang="en_US">The water "blaster" has been one of the most popular toys because it is fun, safe, and easy to operate. The water guns have appeared in many design variations, ranging from the simple squirt gun to motorized water guns. This research proposes a new approach to water gun design. The design consists of a small single burst chamber, and an air bulb is used to pressurize the chamber between shots, creating the sense of multi-shot, large, pressurized tank. Similar to the currently popular Super Soaker, the water in this version is pressurized inside the water channel before each blast. This model also takes advantage of the pressure head between the channel and the reservoir, which is from a backpack, to have the water flow passively into the channel. The user then can pressurize the channel by hand with an air bulb and blast continuously. We implemented a prototype to demonstrate the concept.</dim:field>
