Today we were looking at the ripple effect brought about by the internet and social media. If we pick up a can of soda from the street, post about it on social media and 5 of the people who read our post do the same, the next day will see 6 cans picked up. If the same happens again, then day 3 will see 31 cans picked up and come the end of the week, 19,550 cans will be getting picked up. All because we posted about our aim to pick up 1 can every day. Here we some of the ideas we had and the 'tweets' being generated to put our ideas forward.
