Hot WheelsScience brain teasers require understanding of the physical or biological world and the laws that govern it.
Hot Wheels has finally come out with a car of Men In Black-like gravity-defying abilities!
These cars are of similar size, weight, and speed capabilities to the mass-produced plastic toys kids have loved since 1968, but have one crucial difference in design that allow them to zip past upside-down on the ceiling or cruise by on the wall! What is this difference, and how in the world can it let you drive a toy car upside-down?
AnswerThe difference is a fan set in the center of the car! Think of it as a reverse-hovercar. The fan pushes air under the car up, sucking the car down, creating extra down-force, no matter the orientation! Numbers have been tossed around about F-1s and other high-speed cars producing enough down force at high speeds to drive upside-down, but not surprisingly, it has never been attempted.
