I was sent a pack of sugru to review the other day. It’s pretty funky stuff – out of the packet it’s soft & pliable and feels a bit like blu-tack. You’ve got about 30 minutes to use it out of the pack and it cures in 24 hours, bonds to pretty much anything and turns into a flexible silicone rubber which is waterproof, heatproof (from -50°C to + 180°C) and really very strong.

The pack I got contained 8 mini foil packs of black sugru – according to the instructions it’ll last for six months at room temperature, longer if you keep it in the fridge). Cost via the website: £11 + shipping, or £1.37 per pack. You can get it in smaller packs too. The sugru store is here:

I decided to make some custom-fit earbuds, using my very cheap Philips earbuds – they were less than a tenner and a replacement for my beloved Shure SE115s until I can afford a decent replacement set. The Philips ones sound ok, but let outside noise in really badly (unlike the Shure buds).

The fix was pretty easy to do – roll back the outer rubber bit of the earbud, pop a bit of sugru behind, fold the rubber bit back over then stick the earbuds in your ear. Give it a wiggle to get a good fit, take the earbuds out and leave the sugru to set.

There’s a video on the Sugru website:

Tried them this morning, and whilst it’s not a perfect fit, it cuts out a significant amount of background noise, giving a much clearer sound. I might have another go and use a bit more sugru – I was a bit sparing with it, but the little individual packs hold a decent amount. 5g of sugru goes a long way!

I had some left over from the earbud fix, so decided to see what else I could use it for.

The locking ring on my Opinel pocketknife is metal, and can be pretty slippery if you’re trying to open the blade in the wet. I put a small band of sugru around the metal collar and used the back of a key to give it some ridges for extra grip.

Bonus is there’s now an extra grippy bit when you’re using the knife!

And one final hack using the last bit of the pack (and remember, this is all from one 5g packet), I added a little lump of sugru to the volume dial on my desktop PC speakers. The dial is black, with a tiny black dot indicating the volume you’ve got it set at. Pretty hard to tell how loud you’ve got it set.

Now it’s got a lump where the dot is (should have taken a photo really!) so I can see at a glance how loud the kids have turned up the speakers!
So, all in all, it’s pretty versatile stuff. I’m already looking at other things I can use it for around the house and garden, and the sugru site has some great hacks which I’ll be checking out.
