Photographs from the IfM's first ever Laser Fest event are now available online.

Hundreds of people flocked to the photonic-themed fun day, part of the annual Cambridge Science Festival.

On offer was a chance to see the high-powered lasers in action, race rockets using real laser guns (pictured) and see water being frozen in mid-air.

Such were the numbers that Tim Minshall's talk, Making the Impossible Possible, had a second unscheduled showing to cope with demand.

Photos of the event can be viewed here, also presentation slides and video clips
