We know PhD students like to do things on the cheap… well Ryan Ridden-Harper is doing high altitude astronomy – like the Hubble space telescope – but with no expensive satellite, just a weather balloon. He hopes it will give nice cheap insights into dark energy!
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…
TFW the silliest stories go better than you want…
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
