SciCast Notes:

This can be a fiddly experiment to set up — you need to be extremely careful about draughts, for one thing. So it’s nicely executed here, and the close-ups of soap bubbles are particularly lovely.

I’d have liked to have seen close-ups earlier on, when the vinegar is first added to the bicarbonate of soda, but it’s not as if what’s being done is unclear.

What’s particularly pleasing is showing a partial failure, the fix, and eventual success — it’s hard to get experimental process into a short period of time, but this film manages it. Well done.
