Honey is a weird substance. If you’ve ever drizzled it on your toast or added some to your tea, no doubt you’ve been fascinated and frustrated with the slow and meandering way it emerges from the container or sticks to your spoon. Honey is what’s called a viscous fluid, a liquid that doesn’t flow smooth like water but instead is thick and sticky.
Viscous substances are an interesting topic. Pierre-Thomas Brun and a group of fellow scientists found out what happened when you drizzle a honey-like substance onto a moving conveyor belt in a recently-published paper, and I tried to find out if it could help me with my breakfast-spreading technique. You can find the paper here.
