Non-brittle glue invented. Now we can glue things in space!

Science, Space, Tech Digest news


Awesome news from Kansas State University and their, eh, glue department – an adhesive that doesn’t go brittle when it dries.

Usually, glue loses its stickiness when it loses moisture, but not anymore! This will make it so much easier to glue things in outer space.

According to PopSci, the new glue is made up of peptides, an amino acid, that become increasingly sticky when their pH reaches a level of about 9. Then these peptides form long fibrils that get tangled up in each other and the surfaces they are attached to.

It’s not great for non-porous, smooth surfaces, and there are stronger glues out there. But next time you need to re-attach some heat-resistant tiles on the space shuttle, you will be a happy bunny indeed.
