Blood, urine, hair, beer, oil or fat- What addition to a lime mortar mix makes for the strongest bond- British Waterways, which cares for the country's canals and associated structures, wants to find out because so much of its infrastructure - like Thomas Telford's Pontcysyllte aqueduct - is held together by it. It is looking for teams of students and recent graduates to help it run an experiment this autumn which will involve building mini structures using different mixes of lime mortar and testing their strength to destruction. Trials will take place at the London Docklands Museum on 10 October after a week of build-up.
