Fun with physics - Balls race on the unique flex-rails through various
obstacle courses They accelerate, decelerate, cause chain reactions,
shoot through the loop and run through obstacles such as teeter-totters
and switches. An elevator powered by an XS motor conveys the balls to
the top. The effects are based on various physical phenomena
(acceleration, inertia of mass, centrifugal force, law of conservation
of energy, principle of linear momentum, laws of motion). These are
explained in the activity booklet and can be demonstrated clearly using
various experimental set-ups. Shows how entertaining physics can be!
Contains 690 parts for building seven different models.
Requires 9 V Battery (not included)
