This product is both mesmerizing and addictive! The Pit and the Pendulum is so much more than an elegant desktop execu-toy (although it is that toy!) the Pit and Pendulum demonstrates real science. -- Secured in its oak stand, the all metal pendulum converts kinetic energy into potential energy. The extremely fine sand (included) provides minimal friction allowing the pendulum to swing for extended periods of time. As the pendulum swings it gently "writes" ever changing geometric patterns in the sand. The patterns get bigger then smaller then bigger again as the arc of the pendulum also changes. -- Comes with a stand with bowl-type base, bag of sand, and instructions. Grand Illusions' newly-designed large wood pit & pendulums are available in a natural wood finish pictured with gold plated metal parts, a black lacquer finish with chrome plated metal parts and a cherry finish with gold plated metal parts.

Exceeded my expectations
This is a very nice quality item that produces great conversation and is simply fascinating to watch. I had originally ordered another sand & pendulum--which was very cheaply made (fortunately, it had several missing parts and I returned it and bought this one).
