Endless tracks and obstacle courses await every Hot Wheel’s car lover as they discover the world of physical science. What goes up must come down…or does it? Momentum, force, and friction are just some of the concepts they will understand as cars acrobatically fly before them. Measuring length and weight in various units will help in the identification of the fastest, most efficient car on the block. Mega Loop Mayhem, Shark Cliff Hanger, Wolf Mountain, and hundreds of cars are just some of the play equipment that will have you yearning to come each day! Hot Wheels Rock!
