Here is a video of the “Manometers – the curious case of the coiled manometer” demonstration. The full video is here and shows the rest of the demonstration up to when the funnel (off screen) overflows (on screen).
An index of all the demonstrations posted on this blog can be found here. Don’t forget to follow @nbkaye on twitter for updates to this blog. If you have a demonstration that you use in class that you would like to share on this blog please email me (firstname.lastname@example.org). I also welcome comments (through the comments section or via email) on improving the demonstrations.
