The next two experiments aim to improve the construction of a well using an economic method. Standard extraction of mud or sand with a mud pump can be tedious because it is a physically demanding job. Perhaps it can be done more effectively and without the use of physical force, but in a way :) The film shows a simple modification of the mud pump and a more complicated one, i.e. integration of the mud pump with the pump as a cooperating team. What came out of it? I invite you to the film :) #mud pump #free water #how to make a well
