Just as an aside

.....not really a 'magic' trick, but always gets a giggle or 'ewwww gross'

but here is a cigarette vanish with a difference! (different because everyone sees where it goes....)
Get a King size cigarette and pop it in your mouth as if you are ready to light it (as you will see DON'T try this when it is lit!!

). Make sure at this point that your lips are completely dry. Then with a long and sharp suck in the cigarette will pop 'inside' your mouth. If you suck hard enough it will go right in (oooerrrr missus) and then to finish push it back out with a flick of the tongue!
You can then go on and light up or whatver as the cigarette will be dry (ish)!
If you ask someone for a light, as they offer the lighter up suck the ciggy inside.....often amuses!
