The Sonic Car Launcher is designed to accelerate a Hot Wheels die-cast car. Most die-cast cars this size will work with this project. This is a great project for all ages, but kids younger than six may need help from adults to operate the launcher. Use this launcher as shown below on a smooth floor for high-speed racing fun. Theses instructions will also show you how to modify the launcher to connect to Hot Wheels plastic track for racing fun on many surfaces.
