* Tested with inflatable material (material other than plastic beads with KCL is) to find the hose pipe Before, compare Before (a measure of the estimated flow of material).
* Experiment with a blow to the material. (The material is a plastic KCL) to compare the pipes Before, pipes Before. (The estimated flow of materials).
* test with blower with material (the material that is KCL with plastic pellets) to find the comparative value Before pipe, pipe Before (measure estimates the flow of materials) .
