How does the gecko magic trick work?

well if you cant afford to buy one then listen up

get several elastic bands , cardboard or plastic , sellotape or something sticky and some safety pins !

tie the elastic bands together and attach paper clips to one end , then put the paper clips on the back of your tee shirt so your gecko is hanging there , attach the plastic and out the sticky stuff on the plastic , hide elastic with arm , act casual and do what you do , make the elastic quite tight so you cant see it ping away , i done this and it was pretty bad so i bought it , i recommend buying it , its worth it and better and you get a ring for it to hope i helped ! :)
