What does this roller coaster do?
Learn forces and momentum the fun way with this Connex roller coaster. Create a roller coaster complete with mechanical lift and conveyer belt steps powered from a single gearbox motor (which requires two AA batteries sold separately Order Code <L43AL> to run). Let the ball race through the run with the two different paths.

What does this teach?
Children will learn about the different forces acting on a ball - from gravity to momentum and friction. Show speed and acceleration through play. Demonstrate that the ball can go uphill for short length with its momentum and that the ball gains energy from gravity falling from the lift. The Connex 38608 comes in a handy storage box that doubles as the platform for building the run on. No soldering is required with this kit, all the components can be connected using the supplied wires fitting into the springs on the board. Create different triggers for your run by mixing components with other Connex kits.

This kit should be used with adult supervision and assistance, and is suitable for children aged eight and above.

Rated 2 out of 5 by from Nice idea poorly executed Bought to play with 8 yo daughter. Big issues: 0) Component placement is often vague in instructions, showing too many or no pins on different items without clearly showing which hole to place them in. 1) Motor shafts too long, and tip over the two marble lift mechanisms 2) Because of this, the gearing does not engage the spiral lift without shortening the axel until the gear is in contact with the motor body. 3) The motor also gets lifted out of the baseboard, even once both die axels shortened 4) The orange marble run pieces seem slightly bent outward, making the connections between run and lifts very difficult / impossible 5) The wiring on the motor is too short to connect as shown in the image and instructions, however can be done with slight rerouting and moving the joining springs closer to the motor Overall, more frustrating than satisfying. Only way to make it run is to hold the motor in myself, meaning no play for my daughter by herself. I cannot see that changing for any age up to the teenagers. I also can't see parents sitting idly by as their 8+ child cuts off the end of a motor component. Basically, not bad enough to return but definitely compromised enough to regret.
