Yesterday I attended the launch of the Edinburgh International Science Festival. You can read more about the programme for this year's festival in yesterday's post.
At the event, I caught up with two scientific demonstrations. The first one involved first producing carbon dioxide by pouring boiling water onto dry ice (carbon dioxide in solid form, called dry ice because it doesn't have a liquid phase but turns straight from gas to solid when frozen to very low temperatures). The dry ice then sublimated to produce gaseous carbon dioxide.

The second demonstration involved optical illusions and a plastic model of a rabbit that magically changed shape, but, as they say, you had to be there. It was, sadly for all the bunny fans who read this blog, a demonstration that couldn't be captured on film.
Edinburgh International Science Festival will take place at venues across the city from 23 March - 7 April.
