Maybe a multi-launcher for the compressed air rockets from Make issue 15. Same instant acceleration, though less zappy and cool. Though awesome in its own right.<br><br>Use a compressor to charge maybe 4 smaller pressure tanks which would all launch simultaneous or have arduino stagger the launches (easier to track when a second apart). The rockets could then be crafted with each kid giving it their own art and character with a very cheap amount of consumables.<br>

<br>So, we talked a bit about rail guns last night and then I find this from Make Magazine in my inbox: <a href="http://makeprojects.com/Project/10-Rail-Model-Rocket-Mega-Launcher/243/1" target="_blank">http://makeprojects.com/Project/10-Rail-Model-Rocket-Mega-Launcher/243/1</a><br>
<br>This naturally leads to could we build something like that to launch rockets by railgun instead of igniters. This would, of course, then reduce the need to keep buying those little hobby rocket motors making it more accessible to have kids participate over and over again despite economic means. We basically could get rid of the consumables. Plus, the awesome factor of rail guns comes into play, but this includes kids getting to not only watch, but participate by building a rail gun rocket and see their creation fly.<br>
<br>So, what are the problems that must be overcome?<br><br>JSR/<br clear="all"><br>-- <br><br><a href="http://about.me/josiah" target="_blank">http://about.me/josiah</a><br></blockquote></div></div>
