How do Hot Wheels color shifters change color?
Hot Wheels color shifters change their color through the magic of thermochromatic paint! This type of paint reacts to temperature changes. So when you dunk your Hot Wheels in warm water, it shifts to one color, and when you splash it with cold water, it shifts back or to another color. It's like having multiple cars in one, depending on whether you're playing with them in the sun or in the shade!

It's basically mood rings, but for your Hot Wheels. Warm water = one color, cold water= another. Science!
They don't really change color; they just react to temperature. Warm makes them one color, cold makes them another. It wears out after a while though, so don't expect the magic to last forever.
