This illustration was for an article about Neutrinos by astrophysicist Katie Mack. There had been some discussion in the scientific community about a fourth possible Neutrino. The article referred to neutrinos as flavours. Electron, Muon and Tau. I thought it could be fun to re-imagine them as gelato flavours with a fourth mystery flavour. This illustration appeared in Issue 80 of Cosmos Magazine.
