Hand Buzzers or to some they are called Joy Buzzers, these toys or joke toys are favourites with pranksters or when playing a joke or practical trick on someone. Hand Buzzers have been giving a jolt to victims since 1928 when they were created by a Danish inventor called Soren Sorensen Adams who went on to form a company and a novelty producer. Sorensen also came up with Sneezing Power in 1906, and also the razzberry or Whoopie Cushion, the snakes in a can, and the exploding cigar novelty toys. – So a huge amount of practical and comical jokes all from one guy, very impressive.
The Hand Buzzer became patented in 1932 and the device does not shock or jolt the victim it merely makes a loud vibrating noise which instead gives the victim a shock. I cant help but respect him a lot for devising numerous toys which have been very popular for gag and jokes in over a hundred years. I used to find Whoopie Cushions very funny to use apart from the times I overfilled it and it popped and alongside his other products, stink bombs and small bangers were also used in small doses honest.
