HI guys i thaught id update this thread.After some experimentation i have discovred that Realgar [Arsenic sulfide] works very well once powdred[it crushes easily] and added with most citrus juice[i used grapefruit juice & also tried pineapple ]realgar is easily sourced as a mineral[ebay] so now everyone has the chance to have some fun and can have a go if they wish .
[BUT BE CAREFUL THIS IS POISON AFTER ALL]
I also tried orpiment[arsenic trisulfide]but found it hard to powder and didnt work as well.
