Smartivity Slippery Slopes Friction Slider comes with multiple, swappable surfaces with varying friction coefficients, multiple levels and a singular objective to guide the marble to max points. With 8 different levels of friction coefficients to conquer, it will keep children engaged and focussed on the task at hand.
Use the instruction manual to build the toy. When assembled, slippery slopes friction slider consists of 4 channels arranged one below another, to form a continuous track for a marble/ball to roll through from start to finish. The objective is for you to guide a marble/ball from the start point to the collector at the base using gravity and controlling (using the handles, like a joystick) the inclination of the channels through the different levels. Each level offers a new and unexpected degree of challenge for the ball to roll (since friction coefficients of different surfaces such as foam, sandpaper, plastic, etc. offer different levels of resistance). The gameplay can be made even more challenging by adding further variable obstacles in the form of rubber bands (in slots provided). Everybody is a winner though, because crossing every level awards you some points. The highest points can be won by guiding the marble/ball through all 4 channels, from start to finish (collector basket at the base).
