Kind: research · Impact: low

## In brief

- A water-activated polymer hardens into solid shapes underwater, a property known as hydraulicity in cement.
- The polymer is reported to bond glass fragments.
- The source reports this as a materials science development in polymers.

## Why it matters

Water-activated polymers that set in wet conditions could broaden materials options where moisture normally prevents bonding or shaping, which is relevant to materials scientists and chemists.
