Based on our number one selling mousetrap car kit, The Basic Kit, The Ranch Hand is the first of its kind kit that comes with completely reusable and interchangeable parts. The Ranch Hand was designed to be used as a demonstration model for instructors and/or a reusable kits for students but will also makes for a great science fair project. The mousetrap can be attached and then reattached to any of the three predrilled mounting locations in order to investigate how the location of the mousetrap effects performance. The Ranch Hand comes with three different length lever arms so students can change see how the pulling force is effected by the length of the lever arm. The Ranch Hand also includes three different sized drive axles so students can see how the axle and wheel gearing effects both speed and travel distance. The Ranch Hand also comes with wheel treads for investigating traction and friction. Both CDs and DVD layers are included for investigating rotational inertia. The Ranch Hand comes ready-to-assemble with pre-cut and pre-drilled parts so you can be ready for action in less than 30 minutes and then take it apart and reassembled it all over again. As with all our kits, The Ranch Hand Kit comes with step-by-step instructions that are filled with tons of top secret performance tips and tricks that have been developed exclusively by Doc Fizzix so that you will have all the information you need to make your The Ranch Hand a success.
