Pink and green noodles, a banana candle and a torn-up nappy.
It sounds unusual, but that's what happens when a nanotechnologist shows you how easy science can be.
Dr Michelle Dickinson, also known as Nanogirl, visited second-year Bachelor of Education students at the University of Auckland's Whangārei campus on Monday in what was her first time doing workshops with student teachers at a university.
"One of the challenges we have is we know teachers are complaining that they're not getting enough training in hands-on science during their degrees, and when they're going out to teach they're feeling they're not confident enough to teach science principles," she said.
