Eggers from the University of Bristol have uncovered an explanation for the unpredictable rise of bubbles in the water.

The research findings, published in the famous journal Proceedings of the National Academy of Sciences, can give insight into the behaviour of particles that lie between gas and solid states.

Leonardo da Vinci observed five centuries ago that air bubbles if they grow large enough, will frequently deviate in a zigzag or spiral away from a straight line motion.

However, no description quantitative of the phenomenon or physical mechanism that could provide a rational explanation for this repeated motion has been discovered.

Researchers in this paper have devised a numerical discretization method that can precisely define the interface between bubbles and water, which allows them to simulate their motion and examine their stability.

The simulations of their models closely match high-precision measurements for unsteady bubble motion.

They also show bubbles depart from a straight path inside the water when their radius surpasses 0.926 millimetres.

This is within 2% of measurements made using ultrapure water from the 90s.
