Okay, so I stumbled upon this thing called a “Bruen Pendulum” and thought, “Why not give it a shot?” I mean, it looked pretty cool and kinda simple, so I figured I’d try to make one myself. Here’s how it went down.
Gathering the Stuff
First things first, I needed to get all the materials. This wasn’t some fancy project, so I just grabbed whatever I could find around the house:

- A Sturdy Base: I used an old, heavy wooden block. I don’t use a new one, Just use the old one, It’s good for the base.
- Some Rods:I found Some metal rods.
- A Ball: I took the old golf ball.
- String: I had a roll of regular old twine.
- Screws and Stuff: I found them in my toolbox, just basic stuff for putting things together.
Putting It Together
Next up, assembly. I’m no engineer, but I can follow basic instructions. I started by:
- Fixing the Rods: I screwed the metal rods into the wooden block. I made sure that are enough tall and firm.
- Hanging the Ball:I made a hole into the Golf ball. and use String to link it. And then, I tied the string to the top of the rods, making sure the ball hung right in the center.
- Adjusting:I tied three of the string on the ball and fix on each rods.
The Moment of Truth
With everything set up, it was time to see if this thing actually worked. I pulled the golf ball back and let it go… and wow! It started swinging in this crazy, unpredictable pattern. It wasn’t just back and forth like a regular pendulum; it went all over the place!
I spent a good chunk of time just watching it swing, messing around with the starting position to see how it changed the motion. Honestly, it was way more entertaining than I expected.
Final Thoughts
It is really amazing to see the ball swing! It swings in a very interesting way. I am very enjoy it!
So, that’s my little Bruen Pendulum adventure. It was a fun, easy project that turned out to be surprisingly cool. If you’re looking for something to do on a lazy afternoon, I’d definitely recommend giving it a try!
