To provide a dry and wet power device which can satisfactorily operate even with indirect sunlight.

Active parts 1 of a pinecone are separated one by one and then slightly corroded, bleached, colored, adhered and impregnated with a deliquescent material, and bonded and fixed onto a connecting material 4, and an object to be moved is fixed by bonding to the active part 1. For example, when it is desired to move petals of an artificial flower, a core of the flower is made of Styrofoam, the active part 1 is fixed by bonding to the core of the flower serving as the connecting material 4, and then a petal-shaped object 2 is fixed by bonding to the active part 1, thereby forming a flower-shaped article.
