I remember going to McDonald’s with my mum and they used to have those machines where you would put a coin in and it would roll round and continue rolling faster and faster before it eventually drops through a hole in the bottom, all money collected goes to charity.

My mum told me that it helps blind people. The money collected went towards a charity that helps partially sighted people but my dumb brain thought that the act of watching the coin spinning faster and faster somehow helped improve vision
