What kind of glue is it? Cyanoacrylate (krazy, super, mighty bond) isn't as structurally strong as other glues like epoxy but the baking soda acts like mortar and zip-kicker at the same time. Coupled with the paper click acting as a reinforced bridge, you could be up and running with that headset again in half an hour. If you need more structure for the joint, do the paper clip/glue & bicarbonate; then roll some masking tape around the repaired area and color it with a magic marker. Then douse with more cyanoacrylate and treat with a blow dryer or heat gun. I've fixed broken sunglasses, cellphone cases and a toolbox handle with this method.

What kind of glue is it?
From the Gaelic word súgradh, which means “play,” Sugru can bind to ceramics, glass, metal, wood, and most plastics and fabrics, according to its maker, FormFormForm Limited. (That wasn’t a typo.) It comes in 10 colors, but in the half hour you have before the putty gets too hard to mold, you can mix different-colored Sugru batches together to match, for example, the color of a chipped porcelain vase. Not that you can play to your heart’s content: It costs $12 for 3 packs, $22 for 8, and each pack holds 5 grams, an amount slightly less than a level teaspoon.
Sugru feels like Play-Doh while you’re working it. But once it cures, in about 24 hours, it behaves like what you might expect of silicone. It’s waterproof, will bend a bit, and can handle temperatures from sub-zero to about 350 degrees F. And though you might not be able to get it off a porous material, you can easily remove it from non-porous surfaces by cutting it or even simply rubbing it off.
How we tested
In our tests, we tried it out every way we could come up with. Our favorites included:
Adding protective feet to items whose bottoms weren’t flat enough for adhesive-foam and similar store-bought pads;
Making bumpers for the corners of a cellphone, adding protection and, due to the contrasting color, better visibility;
Fixing items that needed a little extra support, such as a snapped microphone boom on gaming headsets;
Filling in gaps caused by either missing pieces (a chipped ceramic container) or surfaces of different composition, which most adhesives won’t join.
What we found. As we expected, a pack doesn’t go very far. Sugru sticks adequately to non-porous surfaces but not as well as a true adhesive. It isn’t as soft as some other silicones once cured, and it’s not especially strong. And while you can compress it without problems, it didn’t handle stretching well.
Bottom line. We wouldn’t use Sugru where failure of the bond could create a safety or health issue. But in cases where filling a gap is essential, a structure requires some reinforcement, or surfaces don’t align well, we found it fun and useful—there are many situations where the usual adhesives wouldn’t apply. Still, we recommend it for non-critical repair tasks.
