Scream if you wanna launch Manchester Science Festival!!!

The festival in conjunction with acoustics expert Professor Trevor Cox of the University of Salford are on a mission to find out what makes the most chilling scream.

Professor Cox has designed a website featuring a range of cries, howls, wails, screeches and shrieks and is asking the public to vote on the best scariest with the results to be revealed in time for All Hallows’ Eve.

If your brave enough go and take a listen… and don’t have nightmares!
