On a cracking Melbourne afternoon we spoke to Mitchell Horrocks about his time and work in Uganda. He first travelled to Africa in high school, and since then learned about their disease problems due to unclean drinking water. But every problem is a solution waiting to happen, so Mitchell has designed an apparatus that can sit on an existing cooking setup and purify water at the same time. Have a look at his crowd-sourcing page here.

Heston Blumenthal is one of the most influential chefs of our time, and his "right hand man" - and Dinner by Heston Executive Chef - Ashley Palmer-Watts joined us in the studio to talk about running restaurants in different continents. We spoke about his Fat Duck journey, the logistics of setting up Dinner in Melbourne, and the awesome gin they created based on a trip from Perth to Margaret River.
