Plexiglas rods would be best, with luck the available diameters coincide with your needs. You can always wrap clear Mylar around a loose post to carefully snug up the mount Concealing a red LED under each Plexiglas post would make them glow red, just a fun thought. You could arrange a system where the visitor pushes a button to "launch" a particular rocket, for fun or as a way to tie artifacts to their specific descriptions or labels. Might rig up a motion sensor to "launch" the rockets when visitors approach. Have fun with it, and always listen to the conservator! Curtis From: topladave .

As a conservator I would not use wood, which can contain acids that can corrode metals and damage other materials. I suggest making round supports from plexi tubes with square bases for mounting to the exhibit platform. Cheers! Dave David Harvey Principal Conservator & Museum Consultant Los Angeles CA.
