# Improvised Overhead Stirrer by Uemura This is the Uemura design of an overhead stirrer. Take a glass rod which fits very well in a glass tube. Drill a hole in a cork stopper and mount the glass tube. You can use hot glue to fix the tube to become more stable in the cork. The glass rod can be shaped at its one end to simple u- or t-forms for stirring. Use glycerine between the rod and the tube for proper gliding [This construction is not usable for pressure or vacuum but allows reflux if the rod and tube fit tightly]. The other end of the rod is attached to a 3-5cm piece of rubber vacuum tube. Then take a kitchen mixer from your wife, saw off one of the mixer and mount the shortened piece in the vaccum rube. This construction vibrates, but this a welcome feature since the whole system is now elastic and can't break. Uemuras one run for four hours without any problems. BTW, this was on a Urushibara reduction, one of the three necks has a tube to 'move' the hydrogen at least a bit away from the motor.
