8．We are all attracted by magicians，who seem to be able to perform impossible acts，such as pulling white rabbits out of hats and cutting a woman in half．Like all performances，though，a magician's real secret is in practicing thoroughly before showing anyone their tricks．
Magic Matchsticks
You will need
•several matchsticks
•a handkerchief with hems （折缝） along the edges
What to do
1．Show the audience a matchstick．
2．Take a clean cotton handkerchief from your pocket，and shake it out，showing both sides to prove you are not hiding anything．
3．Wrap the matchstick in the handkerchief．
4．Ask one of the audience members to feel the matchstick inside the handkerchief，and break it．
5．Shake the handkerchief，allowing the unbroken matchstick to fall onto the floor!
The secret
Before you begin the performance，slip a matchstick into the hem of the handkerchief．When you ask someone to break the wrapped-up matchstick，make sure that they break the one hidden in the hem （when they feel it，they will think it is the one they saw you wrap into the handkerchief）．
It's a good idea to have two or three handkerchiefs with matchsticks already secretly in the hems，as your audience is sure to be shocked and ask you to do the trick again．But don't let them realise that you are changing handkerchiefs，or they may become suspicious!
