More action with the Element Releaser from the GraviTrax PRO line. The first stone that connects three levels and interacts with balls. This element creates dependencies across three levels. On the top level, balls can roll into the Releaser from two inputs. As soon as a ball rolls through the Releaser on the bottom level, a ball is released from the top level and exits the stone on the middle level. This allows the Releaser to be integrated into the track as a delay and ball trigger. A fireworks display of ball explosions can occur. Manual loading is not necessary.

GraviTrax is a flexibly expandable, interactive marble run system for children aged 8 and up: With GraviTrax, children, teenagers, and adults not only build simple marble runs. They create unique marble run worlds. By freely designing the marble runs and exploring the rolling behavior of the balls, understanding of science is sharpened, and gravity is experienced up close. The GraviTrax universe includes three exciting lines - Core, Pro, and Power. All GraviTrax lines and products can be freely combined. With countless expansions featuring classic building elements or stones that enable special actions and tricks, the GraviTrax universe can be infinitely enlarged. This allows everyone to tinker, experiment, and build beyond their limits.
