Boy racers were in model car heaven when Top Gear star James May joined them to launch a national Scalextric competition at John Kelly Boys' School.
Pupils at the school, in Crest Road, Neasden, got the chance on Tuesday to meet the motoring expert and Top Gear presenter James May and World Slot Car Champion James Cleave.
The aim of the Scalextric4schools challenge is to inspire the students to consider taking science and engineering-related subjects.
Secondary school children are asked to design their own Scalextric car, manufacture it, fit it with a motor and a drive train and then race it on a standard Scalextric track.
The overall winner will be chosen by race position and an evaluation of the quality of the car and of their portfolio, which will explain the design and manufacturing process.
