this is an easy trick to perform. this is it.

the bottom of a soda can is indented inwards with a lip on it.
when you slam the coin (signed) into the bottom, angle the bottom of the can slightly upwards. when done right the coin will stay in that indent and rest on the lip. you can now show your hand empty.

pass the can bottom end down into your other hand you just showed empty. the coin will fall right into your hand without any noise.

you can now show the other hand empty.

ok, by now you should be holding the can upright in your hand. flip the can top end forward so that it is laying on your hand and on top of the coin.
show top, still sealed. spin the can in hand and still on top of the coin. show the bottom has no hole.

now, when you pick up the can with th other hand also grab the coin.
the coin should be behind the can held by your thumb. start to shake the can, but not too much. you can use your own patter here....something like, "if you listen closely you can hear the coin in the can."
as you shaking the can your really slideing the coin up to the top.
remember angles here. the top of the can is slighty angled towards you. carefully slip the coin over the top lip of the can. when it gets on top it will cling. shake can alittle after its sitting on the top. you want the cans mouth facing you as well so when you drop the coin on top its right on the mouth of the can.

at the same time you pop open the can push the coin through the mouth. they will never know you were openning the can and pushing the coin in at that moment if you open the can with a huge gesture.

start to pour the can out and the coin stops at the mouth from the inside!

thats it! your now your own mindfreak!! hope you like it!
