While your specific request is not going to be exposed/revealed here...
I would suggest going to Public Libraries or at your school....you should find magic books there...as well as mentalism tricks in these books.
No $$ reasons for not doing that...Right ?
See, I would do that. I learned how the razor swallowing trick was done; and that's the problem. It's a hick town, so the library only carries outdated magic books. (I did pick one neat trick up, it involves blowing smoke from an empty corncob pipe. If my chemistry knowledge serves me, though, I may only want to do it with a mouthful of tums; gaseous hydrochloric acid tends to burn things. On a side note, that's probably why the trick faded into obscurity. If you inhale with one of these puppies, it'll reduce your lungs to a puddle.)
