Video of the Week

Pouring ketchup out from a bottle is one of the more annoying things in our everyday lives - sometimes it stubbornly refuses to come out, and yet at other times a whole glob of it suddenly gushes out! This frustrating behaviour is due to ketchup being a non-Newtonian fluid.

In this video, George Zaidan uses simple and entertaining animations to explain the physics behind non-Newtonian fluids and how they can suddenly transition from solid to liquid phases and back again.

The Video of the Week is a newly introduced feature. Each week, we will highlight a new physics-related video. The selected videos will cover a wide variety of issues, ranging from academic to pedagogical or even introspective in nature. Through these videos, we hope to inspire students, broaden the horizons of their physics knowledge and stimulate thinking and reflection. Stay tuned for more exciting videos in the coming weeks!
