Help Detergent Suicide In the UK

[Schweppes]

Hi, I'm looking to find out what I would need to purchase in order to execute ctb by hydrogen sulfide. I'm looking for things I can buy in stores (preferably without ordering anything of the internet). I'm also open to other options. I'm interested in SN but I do not know how to acquire it in the UK

There is a very good video on you tube on detergent suicide. I don't remember the exact name but u can search for it. The video is very technical at the also informative .
