The Sling-Shot is the worlds fastest rubber band powered racer and will travel a 5-meter distance in less than 1-second. The Sling-Shot success comes from it's ultra-sticky foam wheels and Doc Fizzix's unique pulley launch system that is designed to maximizing the transfer of potential energy into the kinetic energy with almost no loss of energy. The Sling-Shot Kit comes ready-to-assemble with pre-cut and pre-drilled parts so you can be ready for action and racing on the same day. As with all our kits, The Sling-Shot 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 The Sling-Shot Kit a winner. The Sling-Shot takes a bit work to build than other rubber band racer kits and some cutting and drilling is required by the builder. This is a mini-class pack of 10-kits, order as many kits as you need for your next large group activity.


  • Pulley launch system
  • 2-inch ultra sticky foam wheels
  • Light weight design
The Sling-Shot uses our all new revolutionary pulley launch system that is designed to maximized the potential energy of a stretched rubber band into kinetic energy with almost zero loss of energy. The secret to the pulley launch system is that it is designed to stretches the rubber band instead of winding it as is common with other rubber band vehicles; this system will double the power output and double the torque of the system causing the vehicle to "rocket" off the start line with an almost unfair advantage.

Ultra Sticky Wheels:

The biggest challenge with all high-speed racer is wheel traction, if wheels do not have enough traction then the racer will spin it's wheels at the start wasting precious energy. The Sling-Shot Racer comes with two ultra sticky foam wheels that are made from a lightweight urethane that is designed to grab the floor and provide maximum traction and acceleration. While the rest of the field is spinning their wheels at the start line your racer will be flying across the finish line in record time.

As with all our top rubber band racer kits, The Sling-Shot Kit includes our "easy-to-wind" and "snag-free " string release system that will not tangle or snag for increased performance, a technique developed exclusively by Doc Fizzix.
