Double block and tackle to gain power
Assemble a combination of one single and one double block. The double block is attached to the ceiling. Attach the lifting rope to the lower single block first. Let the rope go up into the upper double block and return to the lower single block. The lifting rope turns one last time in the lower single block, goes up through the upper double block and then runs on through a single block until it reaches the first scale, which in turn holds up the first fabric bag containing three bottles (= 4,5 kg). The second scale is fixed under the lower single block and under it a second fabric bag that can be loaded with bottles (balancing weights).
