Hey everyone, it’s your buddy back again with another little experiment. This time, I got my hands on something called a “toy coil spring.” Now, I’ve seen these things around, mostly in kids’ toys, but I never really gave them much thought. But the other day, I was in a store and saw a pack of them for a couple of bucks, so I thought, “Why not?”

First thing I did was just play around with one. I stretched it out, let it go, and watched it snap back into place. It’s kinda mesmerizing, to be honest. Then I started thinking about how these things actually work. I mean, it’s just a coiled-up piece of metal or plastic, right? But it’s got this stored energy that gets released when you let go. So, I did what any curious person would do – I took it apart (don’t worry, I had a few spares).
Experiment time!
I grabbed one of those glow-in-the-dark ones – figured it would be more fun. I carefully unwound it, trying to see how tightly it was coiled. Then I tried winding it back up, which was a bit of a pain, but I managed. After a few tries, I got pretty good at it. This got me thinking about the different ways these springs are made. I’m no expert, but it seems like the material, the thickness, and how tightly it’s wound all play a part in how it behaves.
- Experiment 1: I took two different springs – one metal, one plastic – and stretched them to the same length. The metal one felt like it had more resistance, and it snapped back quicker.
- Experiment 2: I found a bigger, thicker spring and compared it to a smaller one. The bigger one was definitely harder to stretch and had a lot more “spring” to it, if you know what I mean.
Then I started looking around the house to see where else these springs are used. Turns out, they’re everywhere! I saw them in pens, in some kitchen gadgets, and even in my old alarm clock. It’s amazing how such a simple thing can be so versatile. I even remembered seeing them in some old toys I had as a kid – those little figurines that pop up when you press a button. It all makes sense now!
So, what did I learn from all this? Well, besides having a bunch of unwound springs lying around, I gained a new appreciation for these little guys. They’re a perfect example of how simple engineering can be used in so many different ways. Plus, they’re just fun to play with! I might even pick up a few more next time I’m at the store – maybe some of those jumbo-sized ones. Who knows what I’ll come up with next?
Anyway, that’s my little adventure with toy coil springs. Hope you found it interesting. Until next time, stay curious!
