Dr Marieke Navin, from MOSI Manchester, recently participated in the refurbishment of a huge neutrino detector called Super Kamiokande beneath the Japanese Alps. She says “The detector is a cylinder 40m diameter and 40m tall holding 40,000 tonnes of ultra-pure water. This experiment is iconic in the world of neutrino physics and won the Japanese part of the Nobel Prize in physics in 2002. There is a famous orange dinghy that the scientists use to navigate the top of the tank and riding in that was thrilling!“

So what do these incredibly elusive particles get up to and what is their role besides ignoring nearly every other bit of matter?
