Watford students received a special lesson from TV scientist Lord Robert Winston at the opening of a new technical learning centre today.
The professor and television presenter conducted experiments at the Watford Grammar School for Boys as its new science, technology, engineering and mathematics (STEM) hub.
The project, which is in conjunction with Imperial College London, will see the new facility opened up to pupils from other schools.
The STEM hub is part of a drive to get more pupils interested in science, engineering and technical professions.
It has already been through a six month pilot in which 11 other schools were involved.
Following the opening Lord Robert Winston said: "It is a pleasure to be here and to be involved in the opening of the Imperial College Reach Out Lab STEM hub within Watford Grammar School for Boys.
“The Reach Out Lab at Imperial College, and the hub within WBGS, share a common aim of raising aspirations and attainment within the STEM subjects through hands on learning.
"This is a promising start to our aim of encouraging other universities and schools to engage with their local communities in practical learning."
