A few years back, I published something that ruffled a few feathers: a DIY experiment where, with about $20 worth of parts and 20 minutes of your time, you could replicate one of the most important experiments in physics history — and maybe even call some of Einstein’s assumptions into question.

It’s called an interferometer. Simple, elegant, powerful. And the best part? You can build one yourself right on your kitchen table.

I didn’t just write this for the physicists. I wrote it for the doers, the makers, the curious folks who don’t mind asking the big questions. The ones who still believe science should be observable — not just theoretical or locked away in a lab somewhere.

Why This Matters More Than Ever

Interferometry isn’t just an old-school science experiment. It’s at the heart of some of the biggest discoveries of our time.

In 2017, the Nobel Prize in Physics went to the team at LIGO for detecting gravitational waves — literal ripples in space-time — using interferometers the size of football fields.

In 2023, the Nobel Prize again highlighted light’s wild behavior, awarding Pierre Agostini, Ferenc Krausz, and Anne L’Huillier for capturing electron movements with attosecond pulses of light.

The same principles I’m showing you in this DIY setup are what power those billion-dollar breakthroughs. The difference? I’m handing you the keys — no lab coat required.

This Experiment Has Traveled the World

Since I first published this guide, it’s been shared, cited, and re-created across classrooms, maker spaces, and research groups worldwide.
It’s been referenced on platforms like Instructables and discussed in forums where real experimentation still means something.
This little experiment has helped spark curiosity in thousands of people — and it’s still going strong.

I’ve been fortunate to receive awards and recognition for my work in engineering, media, and innovation, but honestly? This one remains one of my favorite things I’ve put out into the world. Because it invites people to look — not just believe.

Wanna Try It?

Here’s the deal:

Basic parts you can grab at a hardware store

About 20 minutes to put it together

A real chance to watch the laws of physics bend right in front of your eyes


You don’t need to be a scientist to ask good questions. You just need the guts to try.
