This is a hot wheels car that will change from blue to purple depending on the temperature. You can use water or the freezer to change the temperature. You could probably even leave it out in the cold weather…or in the heat in summer.

Love the style of this blue car, so cool!
This would be great for my grandson. He collects cars.
