how did you determine the pulley size and how did you determine the speed.
also how much water did you all use in the bottles?
I put about 100g in the bottles.
The pulleys were the same used in 3D printers, which made them plentiful and inexpensive.
Speed was determined by testing the assembled machine. Play with yours and let us know your results!
