We can t say too much about the task itself as it is under wraps until the day. Suffice it to say that it will involve water, lifting and careful placing of an item. Whatever they build they will have to understand pulleys, gears, electric motors, soldering and have a sense of experimentation. Team work is essential. Prizes are on offer for successful teams, including vouchers for the London Eye and cameras.
Heroic failure is as important as success.
The day promises to be great fun.
