A Dutch Engineer’s Pet Goldfish Just Made History After He Built an Incredible Contraption to Get Blub Behind the Wheel
Thomas de Wolf got bored at work.
What he built to fix that just landed his pet goldfish in the record books – and could change the lives of millions of Americans who can't drive.
You're not going to believe what Blub the goldfish pulled off last month on live television.
Blub the Goldfish Sets a Guinness World Record
De Wolf, a computer engineer from the Netherlands, built a four-wheeled vehicle with a water tank where the driver's seat should be.
The car steers itself by tracking wherever the fish swims inside the tank.
Blub glides left – the car turns left.
Blub drifts right – the car turns right.
On January 23rd, on the set of Italian TV series Lo Show dei Record in Milan, de Wolf dropped Blub into the cockpit and let him loose.
The little fish drove 40 feet and 3.46 inches in under sixty seconds – nearly triple the minimum distance Guinness required.
Official Guinness adjudicator Sofia Greenacre tracked every inch of it, counting each rotation of the color-marked wheels to confirm the distance.
When it was over, show presenter Gerry Scotti summed it up simply: "I don't know if it'll be a world record, but we definitely saw something very sweet and very futuristic."
It was a world record.
After receiving his certificate, de Wolf had only one question: "How am I going to explain to Blub now that he has a world record title?"

The Motion-Sensing Technology Behind the Goldfish Car
A goldfish driving a car is funny.
What's underneath it is serious.
De Wolf said he built the contraption because his engineering work had become monotonous – he wanted to show people what motion-sensing technology could actually do when you stripped away the corporate PowerPoint presentations.
"The objective is to show people what is possible to achieve with this kind of technology, even when it's not necessarily something 'serious,'" he told Guinness.
But here's what he said next – and this is the part that matters.
The same system that lets Blub steer a car could help people with mobility disabilities do the same thing.
No hands required.
No joystick.
A high-precision camera locks onto the fish's position inside the tank and converts every movement into a directional command – the whole car responds in real time to wherever Blub decides to go.
Scaled up and refined, that same principle could give independence back to Americans who've lost the ability to operate traditional adaptive controls.
"I would love to maybe one day be able to help people with mobility issues," de Wolf said.
America's Got Engineers Like This Too
It would be easy to write this off as a European quirk – a bored Dutch guy playing with fish.
Don't.
America has always been built by people who solved serious problems with outrageous creativity.
The Wright Brothers looked like two bicycle mechanics from Ohio fooling around with kite fabric.
The first computer mouse looked like a wooden box with a wheel attached.
Every major assistive technology breakthrough in American history started with someone doing something that looked ridiculous from the outside.
De Wolf's goldfish car is that moment.
Motion-sensing systems are already at the frontier of mobility assistance – researchers have spent years developing sensor technology that translates eye movement, breath patterns, and subtle head tilts into wheelchair commands for patients with ALS, spinal cord injuries, and advanced multiple sclerosis.
The gap between a fish tank on wheels and a fully functional adaptive vehicle is engineering work – and engineers have closed bigger gaps than that.
De Wolf's proof-of-concept just showed the world the sensing mechanism is solved.
A camera can track a moving object in real time and convert position into directional commands.
One Fish, One Record, One Big Idea
Blub doesn't know he's famous.
He's back in his tank somewhere in the Netherlands, probably swimming the same slow loops he always has – except now every one of those loops represents a little bit of history.
De Wolf gave an ordinary Tuesday a world record and a genuine idea worth pursuing.
That's what good engineers do.
They make you laugh at something and then, three paragraphs later, make you realize it wasn't a joke at all.
Blub drove 40 feet.
The next version of this technology could take someone's grandmother all the way to church.
