This trick was performed very well by David Blaine . The magician is seen to roll some thread into a ball in his fingers . The thread is then placed in his mouth and he appears to swallow it. The magician appears to be in pain , when he bares his stomach and visibly pulls the thread out from it .
Thread , you will need two pieces of the same coloured thread .
"New skin" latex clear paint for covering cuts and grazes or other brand of latex paint. This liquid paint is normally available from pharmacies .
You need to paint a one to two inch square area on your stomach with the latex . When it dries you can pull it gently away from the skin to form a pocket .
