Dear Science: September 5th, 2018

While Allan is away in Tuscany enjoying sun and wine, we gather in our little studio with Marcus Jones, also professor of Chemistry at AUT, to talk about science. 

And today, we cover a tiny air leak that could have proven very dangerous for the International Space Station. We also talk about daylight saving: why? what? and is it really necessary? Finally, we wonder why finding an adequate substitute for salt is so tricky, and discover that MSG might be the answer (!)
