it is possible to use a crystal ball to scry into to see the future..the only thing is what people dont understand is you can actually do it with anything ..i.e...looking into a cup at tea leaves.or even in a glass of water..you can either have the gift of a seer or not..i use a crystal ball and i have purposely not trained my vision totally into that ball as if i did that i may not be able to work without it..and sometimes i leave it at home when i am working usually for safety reasons.....some of the gypsys that call around peoples houses are not very good they will usually tell you that you have been cursed and if you give them money they will remove the curse...its just a scam..they are tinkers coming into towns to earn money...i know some real romanys and they have the gift..crystal balls are energy tools and i have a genuine one and it is very powerfull..a lot of them in the new age shops are just glass,,with fancy price labels...if you have any other question i will come back to you mullein
