The advice is given through experiance , we don\'t want to see you hurting yourself, if it came across as snooty or wise ass it was not meant that way.
You could just get a cheap latex hand of ebay for what you want to do, cost you less than buying stuff in, also there is a guy selling hand moulds cheap

Just fill it with gelatine, you should be able to get something similar locally, save a lot of messing about, if you do it the way you describe i don\'t think you are going to get anything useable, when you yank out the hand, most of the plaster will shift around and it will just be a mess.
