The idea of magnetic shoes that allow you to walk on the ceiling may sound like one of James Bond ‘s devices.
But the gadget is just one of many wacky inventions brought to life by Colin Furze, a plumber-turned-inventor from Lincolnshire.
Furze has been inventing mind-boggling gadgets since 2006 (albeit with a self-reported ‘disregard to health and safety’), and has since amassed over five million subscribers on his YouTube channel .
Speaking to the Mirror Online ahead of National Inventor’s Day on February 10, Furze revealed which inventions he’s most proud of, and his tips for other aspiring inventors.
Furze was originally a plumber, and his early inventions were made in an attempt to make his job easier.
He told the Mirror Online: "I invented some plumbing tools for work because I thought there must be an easier way to get the job done.
"As a result, I started tinkering with more and more and wanted to share my inventions with anyone who had a desire to watch!"
People really started to pay attention to his videos after he uploaded a video of an enormous motorbike he had created.
He said: "One of my first inventions that I uploaded to YouTube was the world’s longest motorbike back in 2008 which was a World Record at the time and my YouTube channel really developed from there."
Having uploaded over 200 videos to YouTube, you might think it would be hard for Furze to single out his favourite invention.
But he decisively told the Mirror Online: "I ‘m most proud of my magnet shoes.
"They were cheap, easy and they let you walk upside down and my subscribers reacted brilliantly with them, the wackier the better!
"Creating a home-made hover bike was also a highlight as it was the first invention I made that actually left the ground!"
As with most things, with every successful invention are some failed attempts.
Furze said: "I made a bacon cooking machine that refuses to cook bacon. It just twirls it and burns it.
"The best way to learn is from your mistakes, and you’ve got to persevere."
While Furze is remaining tight-lipped about what he’s currently working on, he revealed that it involves a 3D printer, which he described as ‘great fun.’
Furze also had some advice for other aspiring inventors out there.
He said: " No idea is too stupid. Just go for it.
"You don’t have to be amazing at maths or science, you’ll be surprised how much you can learn if you set your mind to it!"
