A toy includes a first enclosed portion having a first bore and a second enclosed portion having a second bore. The first enclosed portion provides a gas pressure from the first bore to enter the second enclosed portion via the second bore. The toy also has a rotating member rotatable situated in the second enclosed portion and a plurality of fins. In addition, the toy includes a pointer element situated in the second enclosed portion which is coupled to a center portion of the rotating member. Thus, when the gas pressure entering from the second bore is applied to at least one of the plurality of fins, the rotating element rotates the pointer element.
