This one-hour introductory workshop is for those who would like to use the abrasive water jet cutter housed in the Advanced Prototyping Center at Wright Lab.  These machines use high pressure water to accelerate finely crushed garnet to three times the speed of sound.  The resulting jet can quickly abrade its way through a wide variety of materials.  We will cover basic usage and capabilities, some specific advantages and disadvantages, and why using a little bit of sand and water can accelerate your project.
