Here’s how to transform plastic bottles into strong, versatile string

Add as a preferred source on Google

Do you own a small block of wood and a knife? Looking for something MacGyver-esque to do with all those plastic bottles you’ve got piled up? Constantly find yourself short of string?

If the stars align in such a way that you answered “yes” to all three of the above questions, then you may be interested in a nifty “survival hack” demonstrated by YouTuber Grant Thomson in one of his latest videos. As the owner of the “King of Random” YouTube Channel, Thomson makes videos exploring a wide range of “life hacks, experiments, and random weekend projects.” In this particular video he teaches us how to make near endless supplies of strong plastic string using the most basic of tools.

The “hack” involves cutting a small block of wood and then sticking a knife into it to form a makeshift blade. Into this, Thomson then feeds a bottle, which — provided the blade is positioned correctly — cuts incredibly thin strips of bottle. Pulling the bottle then transforms it into string. Using just a few bottles, he ends up making more than 1,200 feet of string.

That’s not his only similar hack, either. Inspired by his string-making success, Thomson then goes onto fashion the string into plastic ropes, using a previous contraption he had created.

“I’ve seen soda bottle string, but with my rope-making machine [that I] recently created, it made me wonder what would happen if I put the two together,” he told Digital Trends. “Many comments were asking me to combine several ropes as well, and this was the perfect opportunity to try that as well to see what would happen.”

As for practical applications … well, they’re pretty much what you would expect. “The practical applications for soda bottle rope are probably the same as anything you could use rope for I imagine,” he said. “If you got the strands thin enough, it would be even finer.”

Well, that takes care of one part of our zombie apocalypse survival kit. Now we just need someone who can tell us how to fashion discarded cable ties into a bludgeoning tool…

Hyundai isn’t giving up on hydrogen cars, but don’t expect one in your driveway anytime soon

Hydrogen cars have spent years in the same waiting room as flying taxis. They’re always almost here, but no commercially available product exists for interested buyers. So when a Hyundai manager pushed back on the obituary, I was immediately curious.

To be clear, Hyundai hasn’t announced a new car. The big news here is that its Australian arm says hydrogen is “not dead” for passenger cars. Apparently, the automaker is still evaluating a next-generation hydrogen fuel-cell car if it can find buyers (via CarExpert).

AI doesn’t have to turn evil to put you at risk

An AI assistant that agrees with everything you say might feel like the perfect companion — until you need someone to tell you you’re wrong. That’s one of the more immediate dangers behind the idea of AI “going rogue.” A chatbot can cause harm without developing intentions of its own. It can reinforce a false belief, encourage an unhealthy attachment, or follow instructions planted by someone trying to hijack it.   

On October 15, AI safety company Alice announced new software to address those everyday risks. Working separately with Inflection AI and AI21, the company says it helped train NVIDIA’s Nemotron models to resist harmful conversational behavior and malicious instructions while preserving their usefulness.

Elon Musk has revealed ambitious plans for Neuralink, and they go beyond controlling computers with your thoughts. The company is developing two brain implants, Telepathy and Blindsight, aimed at helping people with paralysis and severe vision loss. Musk also believes future advances could help people regain control of their hands and legs by reconnecting the brain with their limbs.
