Professor Rod Boswell from ANU shows off a nanosatellite and explains how they are revolutionising the space industry.
There’s been a lot of news about the electrician who got busted hiding his phone/PDA in a foil Twisties packet to prevent his company from tracking him… so he could go play golf.
So I decided to give it a whirl, in some chocolate wrapper. And then try out the microwave. but that wasn’t so successful!
From Physics in the Pub 2016, a great set from Leon Twardy about sound waves, how microphones work, and how an acoustic guitar steals energy from the future.
The Rubens Tube is a really complicated demo that seems simple. Once you start thinking about it you realise that sound antinodes are points of oscillating pressure, so the flames shouldn’t be stable peaks – they should be going up and down at the frequency of the wave!
And if you change the gas pressure a lot the nodes and antinodes reverse position! Wish I’d thought these points through before Derek asked me to film this!
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!
