Stopping demo

On the 20th of March 2013 we went to a stopping demo on Grey Street there was a man who was running it. They put out three pictures on cardboard of people the cardboard was in a triangle shape and in the middle of it was tomato sauce the cardboard was spread out but only one of them got ran over. There were two people in a car they did a different speeds until they hit the cardboard first they did 20 and when we stop he stopped and he missed the cardboard then he did 50 and when we said stop he stopped and missed the cardboard again then he went 60 and when we said stop he stopped but he hit the cardboard and tomato sauce came out! It was teaching us not to go fast in a car and to keep our seatbelts on until you stop.
