9V Motor Fan Cap by Jbonasera

Last crawled date: 4 years, 12 months ago

This set of caps will fit onto the shaft of a 9v motor to turn it into a fan. The fans can be used to push air, of course, but are powerful enough to propel low friction carts across a surface. Several fans mounted onto the same cart serve as a good demonstration of balanced forces.
