Fischertechnik Rolling Action
Metal balls race on the unique fischertechnik flex-rails through various obstacle courses. Students can control the speed and acceleration of the balls with the use of a launching lever or the pre-tensioned catapult. They can also create a chain reaction, make the balls shoot through loops, run over seesaws or ride up an elevator with the aid of a counter weight. Contains 270 components (including 11 flex-rails and four metal balls) for building 6 different models.
