Toast and gravity: why it lands butter-side down
It’s often due to rotation and the height from which toast falls — enough time to rotate half a turn before hitting the floor.
Coffee cools faster in a larger cup — really?
Surface area controls cooling rate. Wider cups expose more surface area, increasing heat loss.
Static hair in winter
Dry air reduces humidity, allowing charges to build up and make hair stand out — it’s static electricity at work.
Why ice floats
Water expands as it freezes, making ice less dense than liquid water — that’s why lakes freeze top-down, protecting life below.
Try this at home
- Drop a slice of toast from different heights (carefully) to observe rotation.
- Compare cooling times of hot water in tall vs. wide cups.
