A surprise find of blue wine in the washing up opened up a world of chemistry in the kitchen.
Turns out red wine and purple cabbage show amazing colours as you change their acidity. They are acid-base indicators, due to chemicals called anthocyanins.
Some lovely footage of superconductors weaving their magical levitation spell

It’s not like we planned this out very well…
Just realised I have never posted the Exploding Yoghurt video, back where it all began. Such nice camera work David Wong!
News from the UK today that new tokamak ST-40 has been turned on, so I thought I’d post a little explainer about how fusion works.
Quantum physics is all about the simplest things in the universe. Matter – electrons and quarks (which make up neutrons and protons), and interactions – photons, forces etc.
The difference between the two is a simple rotation. It’s secret quantum mechanics knowledge, says head of ANU Dept of Quantum Physics, Professor Craig Savage.
Here he is proving it:

It’s amazing how liquid nitrogen affects rubber. Turns it from bendy and stretchy into a brittle solid that you can smash into a thousand pieces – a trick that lots of science shows do.
BUT, not so many people know that there is a heartwarming story of community benefit from this seemingly mindless destruction.
One from the archives. I’d give it a hell of an edit these days
OK, I admit, there actually is no yoghurt in this video. But the explosion is fun – try this at home, kids!
