<DIV>I remember a 'toy' in the physics dept of my high school - </DIV>
<DIV> </DIV>
<DIV>It was an iron rod in a upside down "U" shape, with a pair of coils</DIV>
<DIV> [one at each end] and a section of copper tubing on the iron
rod.</DIV>
<DIV>when you tripped one of a pair of circuit beakers connected to </DIV>
<DIV>110VAC and each coil, the copper tubing flew to the other side </DIV>
<DIV>due to magnetic repulsion of the copper tubing [a shorted turn].</DIV>
<DIV> </DIV>
<DIV>A straight iron rod, with a coil at the base, a big cap /connection </DIV>
<DIV>110VAC, etc, and a small section of copper tubing on the side of</DIV>
<DIV>a model rocket [or a pair of rods, and two sections of tubing on</DIV>
<DIV>each side of the model rocket].</DIV>

gun launcher <BR><BR>So, we talked a bit about rail guns last night and then I
find this from Make Magazine in my inbox: <A

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
