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! https://youtu.be/EUCSk5-7Rbw
https://youtu.be/c-r8LKosap4 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.

Just realised I have never posted the Exploding Yoghurt video, back where it all began. Such nice camera work David Wong! https://youtu.be/olzbX-KXxl4
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. https://youtu.be/sG-blChQD4Y
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 … Continue reading How twisting a belt explains the Universe
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. … Continue reading Smashing things… for the good of humanity
