<p>Its a series of tubes! Pneumatic tubes!</p><p>This talk will describe the infamous 2008 and new 2009 ShmooBall Launchers built by Larry, and introduce Dave's 2009 design. This talk will include all of the steps behind the planning and building process for our launchers, as well as the history, and backgrounds for the design. We'll talk about the methods of building, safety considerations for the operator, target and environment, selection of building materials, design considerations and testing. We'll also discuss some of the construction issues, failures and reasons for what may be considered design flaws. Discussion will also be had about improvements made, and how we can improve for next year.</p>
