An old favourite - table-tennis balls hovering in airflow from a hairdryer - with a little twist.
Director's Notes:
A classic and straightforward experiment.
The music is Strauss’ Blue Danube Waltz, of course — it’s a version from here that’s old enough to be in the public domain. That is, it’s out of copyright and made freely available for anyone to use.
SciCast Notes:
I love the opening to this. It’s an obvious 2001 reference, of course, but it’s nicely carried-off — in particular, the touch of slow-motion effect makes a world of difference to the floating feeling of the film.
The music editing is also brilliantly done, in that it’s extremely hard to work out where it chops and changes. A great example of how careful use of music can add to a film.
Great job.
