At the risk of killing the golden goose, we've been having local drug  
stores save their empty pill bottles.  We drill the tops out to and  
bottoms to 5/32 and use a 3/16 inch dowel for an axle, cut the bottoms  
of the bottles off with a band saw.  Just tried cutting the bottoms  
off of 16 oz water bottles after pre-drilling for dowel axles.  We'll  
see how that works tomorrow.

About Challenger Center for Space Science Education

We are a non-profit 501 (c) (3) organization founded in 1986 by the
families of the astronauts tragically lost in the Challenger 51-L  
mission.
Dedicated to the educational spirit of that mission, Challenger Center
programs continue the crew’s mission of engaging students in science,  
math
and technology and foster in them an interest to pursue careers in those
fields. For more information on our diverse programs, including our
network of Challenger Learning Centers, please click to www.challenger.org
