TWO 14-year-old boys from Hurworth House independent school, near Darlington, have won first prize in a national engineering competition.

Alex Strachan and Tim Latter devoted a week of their summer holidays to investigating how efficient water wheels are to win the prize.

They built their own wheel, and, using electronic counters and timers, measured how it performed.

They then wrote an essay on how they would educate a South Sea island people in the use of the metric system using old cola bottles and string.

All this was to enter a national competition sponsored by the National Physical Laboratory, the Department of Trade and Industry, the Institute of Physics and the Engineering and Marine Training Agency.

The boys and their parents were invited to a ceremeony at the NEC in Birmingham to receive their prize.

They each received £100 and a commemorative plaque, as well as £500 for the school science department
