00:00Concrete can fix its own cracks.
00:02This breaks every rule.
00:04Tiny engineered bacteria live inside.
00:07They wait for damage to appear.
00:09When a crack forms, water sneaks in.
00:12This wakes the sleeping microbes.
00:15Bacteria consume embedded nutrients,
00:17then precipitate calcium carbonate, effectively sealing the cracks.
00:22This innovative living concrete repairs itself,
00:25potentially extending structural lifespans significantly.
