Some noisy children have been helping keep the streets clean by secretly shouting at litter bugs! A group of kids in Coventry have recorded their voices into a CCTV camera, so they can tell people off whenever they do something wrong. The idea is that people are so embarrassed by hearing someone shout at them, they’ll stop what they’re doing. The voices behind the cameras say things like “put your rubbish in the bin!” — and even say “thank you” when it’s been done! It’s hoped the talking cameras will stop things like litter and violence on the streets.
