Physics Experiment Ball Handheld Hollow Metal Liquid Pressure Demonstration Teaching Aid

About this item

• Feature: 1. The ball is a hollow ball with many small holes on the wall, and a movable piston on the handle for easy pressing. 2. There 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. 3. The piston is composed of a rubber ring, which is soft and tensile, and will not be squeezed when water is sprayed out. 4. The hollow ball is made of iron material, which has high hardness and is not easy to deform, and has good pressure resistance. 5. The hollow ball is used to demonstrate the pressure transmission of liquid, which is very suitable for physical demonstration in physics class. 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). Package List: 1 x Physics Experiment Ball Note: 1. Arrange the direction in which the nozzles spray the water column in advance, and avoid spraying water on the teachers and students.2. After the experiment, the instrument should be disassembled and wiped clean, assembled and stored after air‑drying, and the metal parts should be coated with a little earth wood to prevent corrosion.
