For this I need a volunteer
Sir what's your name.
?
Do you have a scisors health and safety certificate?
?
-- wei
Do you mind if while we're performing this we accidently cut your head off?
-- OK
Ok, lets get started, here I have a rope and a magic wand.
Please take hold of the magic wand.
Sir, does this look to you to be about half way along the rope?
-- yes
Ok, if you could just take that pair of scissors and make a snip at that half way point.
Lovely, now if you could give back the scissors, for my safety you see.
Now what we've done here is we started with 1 piece of rope. Where did the second piece come from? Nobody knows.
But we can do more, what if we took these two ropes and turned them into one?
This is going to blow your minds, your heads will explode, as you see two ropes becoming one before your very eyes.
You will be soooo amazed you won't be able to comprehend how awesome it is?
Look ladies and gentlemen, two ropes into 1. Isn't this the most amazing thing you have ever seen in your lives.
-- you just tied a knot
what do you mean I just tied a knot?
what would it take to convince you that this knot is a magic know.
I know, what if I make it disappear?
watch closely, see it's gone.
no, sorry that was just a joke.
Ok try again.
ah yes it just moved along the rope, just a joke.
Ok, for real this time.
But I'm sure you're wondering where the know is.
It's in my hand.
thankyou very much.
