Remember When Tiger comic first came out and you got a cardboard Tiger's head on a string and some powder? You had to put the powder on the string and make a 'roaring' sound with it. Never worked but it did cut your fingers. As I recall you got a folded cardboard triangular thingy in The Topper which when you flicked suddenly made a great cracking sound. Frightened my Auntie Rena with mine and my Dad confiscated it.
