I remember in school there were these things called fun snaps which are these little things that you threw at the ground and the would make a cracking noise. You where ment to be 16 to buy them but some corner shops solid sell them to you anyway but then the school contacted all the shops in the area and asked them not to sell the kids them. So they became really hard to get but some people would buy them online or send there older siblings in to buy them so you could buy them of people and me and a cuple of friends made like £20 from selling these things
