Specification:
Item Type: Physics Experiment Ball
Material: Iron + ABS + Rubber
Size: Approx. 31.5 x 8.3cm / 12.4 x 3.3in(manual measurement, there may be slight errors)
Features:
1The ball is a hollow ball with many small holes on the wall, and a movable piston on the handle for easy pressing. 2There are ten gas nozzles in different directions on the hollow sphere, and the pressure received after the liquid is injected will be transmitted in all directions. 3The piston is composed of a rubber ring, which is soft and tensile, and will not be squeezed when water is sprayed out. 4The hollow ball is made of iron material, which has high hardness and is not easy to deform, and has good pressure resistance. 5The hollow ball is used to demonstrate the pressure transmission of liquid, which is very suitable for physical demonstration in physics class.
