Discover lots of mad fun in the Hot Wheels® Color Shifters™ Color Splash Science Lab™ where crazy color change experiments can get out of control! A mad scientist has trapped a Color Shifters™ car under the color change waterfall and is experimenting with all sorts of insane color combos! Can you help the car escape? Find out in this action-packed thrill ride! Launch into action, race your car around the track and release the trapped car to safety. Uh-oh! Looks like you've been nabbed by the mad scientist instead! Hit the release lever and drop your car into the tank below to return the car's color back to normal. Then you can drive up into the Color Clean Machine™ to make sure all the cars go back to their original color. Kids will love the thrill of trying to escape from the mad scientist's lab and seeing all the wild color combinations. Features four different color change zones and comes with three Color Shifters™ cars so kids can experience the excitement right out of the box.
