This is a funny magic trick that is suitable for adult audiences. The effect is a bit naughty but not at all offensive.
EFFECT: The magician ties two hankies together. Three spectators are invited on stage out of whom at least one should be a lady. The lady is requested to hold the hankies in front of her chest. A hanging corner of each hanky is now held by each gentleman. The magician states that the knot will disappear at his command. As he counts to three, they are asked to pull the hankies.
To everybody's amazement, the knot is found to have disappeared but in its place a super size brassiere has appeared! At first instant it seems that the lady's brassiere has somehow materialized there. Imagine the lady's expression when she sees it.
