wrote "I'm visualizing something that holds 4 bottles on gimbals, with an electric motor (small), so that the centrifuge allows the bottles to adjust into the horizontal position as the rpm increases. As the motor slows, the gimbals allow the bottls to settle. When rpm is zero, the bottls hang vertical.
------------------------------------------ you could duct tape the bottles to a mower blade for really fast separation.....just kidding,lucas
