The Hot Wheels Color Reveal 2 Pack holds 2 1:64 scale Hot Wheels Color Reveal cars in a barrel drum, each with 2 surprise decos just waiting to be discovered. Because each car is covered in a Color Reveal coating, the initial reveal is filled with fun suspense! Use the reusable barrel packaging as a dunk tank, fill it with water, and swirl the car in it. Watch as the water changes colour and a new deco is revealed on each vehicle! The surprises continue with more colour change! Simply dunk the Hot Wheels car into cool water to reveal yet another deco and design -- change it back with warm water. Repeat this over and over again to change between the 2 looks! With the 2 included cars, it's like getting 4 cars in 1! Each 2 pack in the collection features different cars, and kids and collectors alike will want to collect them all for tons of colour-revealing and colour-shifting fun (each sold separately)! Hot Wheels vehicles make a great gift for kids ages 3 years old and up who love the thrill of creative push-around play!
