Video of “Momentum, angular momentum, and bendy straws”

Here are the videos of the “Momentum, angular momentum, and bendy straws” demonstration. The full videos are linked from the GIF titles.

Blowing, showing the straw rotation.


Sucking, showing the straw not moving (very much).


This part was not written up in  the main demonstration but is discussed in Alan Mironoer’s ASEE conference paper.
