      Hey there! My favourite plastic is a plastic called polylactide (PLA) – that’s a plastic I work on quite a lot. PLA is made from starchy plants like corn and sugar beets. It’s plant based and also completely biodegradable so it breaks down in compost. It’s even safe to put in our bodies so we can use it for medical implants!

      My favourite ice cream is mint choc chip!

      I think I said I said in our chat that my best experiment was making liquid nitrogen ice cream! That’s not got anything to do with me making plastics – it’s just a really fun experiment! I make ice cream using liquid nitrogen (that’s -196 degrees!) to cool down the cream and sugar – it’s tastier than normal ice cream!
