MetMo Eddy - A Desk Toy Where a Steel Ball Drops Slowly Through a Copper Tube

Normally, when a small steel ball drops into a tube, it's over in the blink of an eye. The MetMo Eddy is said to stretch that fall out into a slow crawl. It's a copper cylinder small enough to fit in your palm, so it looks like a great thing to fiddle with on a desk, and that's what caught my eye.

📸 Product Tour

It fits in one hand. You can see the steel ball through the window.

It breaks down into the steel ball, a threaded cap, and a copper tube with a window cut into it.

It looks like the sections can be joined using the threads.

Connect three sections and you get a long drop path.

🔍 Why It Caught My Attention

You can see the principle at work

The eddy current effect inside the copper tube is said to make the ball fall slowly. Even without an explanation, it makes you go "Huh, why is that so slow?" the moment you see it.

The copper color is beautiful

The contrast between the knurled cap and the smooth copper surface is lovely. Sitting on a desk, it looks like it would hold its own as an object.

You can join the sections

Since you can join tubes to extend the length, it seems like you could play around with different fall times.

🤔 What Gives Me Pause

It's useless

You could use it as a timer or a focus tool, but in the end it's a toy. If the price is high, I'd hesitate.

Price and where to buy are unconfirmed

I couldn't confirm the price or how it's sold. Like the other MetMo products I covered earlier, it may be produced in small quantities.

🎯 Final Verdict

The MetMo Eddy sells the joy of watching rather than usefulness. The copper material, precise finish, and the section-joining structure suit each other well.

If the price isn't unreasonable, it's an object I'd like to have on my desk. Checking the price comes first.
