Important Setup Notes:
Make sure the handle on the bucket is in good condition so as to not detach during spinning.
Setup and Procedure:
- Partially fill the bucket with water.
- Start with the bucket about an eight of a turn in the direction opposite to the rotation.
- Swing the bucket in a vertically-oriented circle with enough speed so that all the water remains in the bucket.
Cautions, Warnings, or Safety Concerns:
- Make sure not to swing the bucket in the direction of the audience in case the handle would detach from the bucket.
- Demonstration may require practice.
- If water does spill, clean it up promptly to avoid any slips/falls.
Discussion:
Insert description of demonstration, how is the demonstration preformed.
