Years of dismissing pendulum experiments as simple made me miss their depth

I always dismissed pendulum motion as too elementary to be interesting. After spending months recording swing times for a personal clock project, I realized how air density and temperature variations affect periodicity in real-world settings. What everyday physics experiments have changed your understanding through hands-on experience?

What often gets overlooked is the humble soap bubble. I spent an afternoon with my grandchildren blowing them, and what started as play turned into a lesson in fluid dynamics. Watching the iridescent colors shift, I realized I was seeing thin-film interference in real time, something I'd only read about in textbooks. The way bubbles merge or pop depending on surface contaminants taught me about surface tension gradients. That casual experiment made me appreciate how complex phenomena hide in plain sight, just waiting for a curious observer.

Heard a podcast episode where they broke down the physics of skipping stones. Trying it at the lake last summer, I realized the angle and spin are everything. Never thought a simple childhood game had so much science behind it, lol.

Wait, you're saying the spin alone dictates how many skips happen?
