ZipString review: the flying string that surprised the whole family

When I first spotted ZipString, I admit I rolled my eyes. “A flying string?” I thought. Surely this wouldn’t hold Cyrus’s attention for more than five minutes. I was so wrong. The moment he picked it up, his eyes lit up, his fingers went into full-on trick mode, and I found myself mesmerised right alongside him. There was giggling, a bit of competitive mum-versus-son-versus-baba H banter, and yes, a minor crash into me, the TV, and the blinds (but no casualties thankfully).

A fun STEM toy that sparks curiosity

Watching him experiment, it was impossible not to notice how naturally he gravitated toward the science behind it. He was calculating angles, timing swings, and testing tricks like a tiny physics lab right in our living room. Lightweight and oddly addictive, ZipString is one of those gadgets that makes you just watch and wonder how it works. It’s impossible not to get caught up in the fun.

Hands-on play that’s social and screen-free

The other thing we love about it is that it’s surprisingly social. Whether it’s teaching me a trick, challenging baba H to a slow-motion duel, or creating new combos on his own, it sparks connection and laughter. It practically begs for slow-mo shots, creative tricks, and those little moments you want to capture on video, but with real amateur footage, not Insta fluff. I didn’t want to spend ages behind the camera because this is the kind of hands-on play that’s refreshingly screen-free for kids, yet utterly engaging.

Why ZipString stands out in a crowded toy room

I can honestly say, in a house full of toys, this one stands out. It’s simple and endlessly replayable. I’ve even caught myself marveling at the tricks he’s invented. Who knew a flying string could become a corkscrew and so entertaining for both nine-year-olds and their mums?

“I love STEM toys, and this one is awesome. You can learn about motion and angles while having fun at the same time. I can’t stop trying new tricks! It’s really easy to use, and I got the hang of it super fast. Sometimes the string gets all knotted, and that’s a bit annoying to fix, but it’s still fun. I really like the coloured strings because they look cool when you do tricks, but I wish they glowed in the dark too, that would be epic! I love making up my own moves, timing my swings, and seeing how far it can go without crashing into anything. It’s really, really cool, and everyone should try it!” – Cyrus
