Blue Fusion is IBM Hursley Park's contribution to National Science Week. It is an annual week-long Science Fair for Year 11 (15/16 year old) school pupils. The aim is to promote the benefits of science, technology and engineering to a younger audience.

Each year, IBM invites local schools to come to the Hursley Park labs and compete in a variety of activities. The activites are designed and developed by teams at Hursley, focusing on balancing education with entertainment. IBM also invites internal and external speakers to give talks on each day.

The event has been running for nine years, and Blue Fusion 2004 was the biggest and most successful yet, with over 500 students attending. Teams of six from 60 schools participated in the main Blue Fusion competition, while 14 teams from Southampton schools took part in the Bright Sparks event for Year 8 (12/13 year old) pupils.

National Science Week is an annual project coordinated by the British Association, and aims to encourage and enthuse students about the fields of science, engineering and technology. The aim is to celebrate science and its importance to our lives, giving people from everywhere in the UK the chance to participate in science activities and experiments, and to engage in science discussions in their local area.
