Colour-related hands-on science activities that beg active participation will be presented by science centre and museum experts from seven countries. Participants will be able to test their colour vision, see how to break white light into a spectrum of colours, and generate and mix colours. They will be able to wander amongst the dozen or so activity tables, staying as long as they like and moving on to the next table as interest dictates.

Consistently one of the most highly rated sessions at the Ecsite conference, the Grand Bazaar returns in a full range of colours.
