Why does a slice of bread (almost) always fall with the topping-side down?

You’re calmly making yourself a sandwich, the doorbell rings, you turn around quickly — thud — there it goes. And of course it lands exactly how you don’t want it to: topping‑side down. But… does a sandwich really always fall that way? And if so, why? In this video from the University of the Netherlands, Minke Berghuis, physicist at the University of Twente, dives into this seemingly simple yet surprisingly deep question. Because behind that annoying little accident on your kitchen counter lies an entire world of physics.

In this short lecture, Minke explains why our sandwiches behave the way they do — and why it’s not just about ‘bad luck’ or ‘negative bias’. Want to know how you can actually increase the chances of a ‘good landing’? Then be sure to check out this video. Along the way, you’ll also learn more about physics: from the weight of your toppings and the exact moment you let go, to Newton’s second law and the role of friction.
