Hot Wheels Color Reveal 2-vehicle pack contains amazing surprises! The small cylinder contains two Hot Wheels Color Reveal cars in 1:64 scale, covered with a special Color Reveal coating. To discover the color for the first time, fill the barrel with water and create a whirlpool for each toy car until you see the water change color. Pull out the toy car and the beautiful decorations that were hidden under the cover will appear! Do you want to change the color again? Fill the barrel with cold water and submerge each toy car for another awesome transformation! Bring them back to their original color by immersing them in hot water! Repeat this over and over again, alternating between hot and cold water. It will be like having two cars in one! The small barrel acts as a soaking tub for Hot Wheels, but is also perfect for storing them! Each two-vehicle pack is sold separately, subject to availability. Colors and decorations may vary.
