摘要:

With the help of a hand‐held jigsaw and a tin of syrup, the little known dynamically stabilized inverted liquid experiment can be demonstrated to large classes. Lengthy effective potential arguments are short‐circuited by a simple inverted U‐tube theory accessible to most. The role of viscosity and wall effects is discussed. The first dynamic stabilization experiment with water is reported.
