Bubbles exhibit backflipping behaviour when colliding tilted surfaces Alireza (Navid) Hooshanginejad
When air bubble in water collide with a tilted surface, some bounce away and then reverse course, hitting the surface again in a “backflipping” motion. These acrobatics are caused by the flow of fluid around a bubble and could potentially be harnessed for cleaning.
Alireza Hooshanginejad at Brown University in Rhode Island and his colleagues shot differently sized air bubbles in a tank of water towards a glass slide. The slide was held flat against the top of the water or tilted …
