This is my favorite toy in my chilhood-----Plasticine.
I like colorful things when I was a child, so I chose plasticine. I think it is a toy that can practice children's creativity. However, I can't use plasticine make a good work without molds. Therefore, my dad always bought a lot of interesting molds for me. Such as somethings that can change the shape of plasticine to noodles, breads or French fries. There are also some special tablewares for plasticine, I usually used plasticine to "cook" a dinner for my parents.
