It is a very mysterious and interesting scientific toy. When hot water or cold water is applied, the color of the train toy changes. The colors of Thomas the Thomas and Disney Cars Lightning McQueen have also changed. Besides that the colors of trains and buses change. This toy is a wonderful educational toy in Japan. Children enjoy surprisingly.
Wheel loader car, pickup bus, SL locomotive, N 700 series Shinkansen, crane car, container truck, everyone color changes. When it gets warm, the color changes. When cold water is applied, it returns to the original color. Children around the world will love this wonderful, fun and interesting toy. The educational toys are wonderful. I love electric trains and bus toys, Disney toys, Thomas the Tank Engine 's toys.
