Hello! I was wondering how I could make a pressure chamber to aid some chemical reactions? The higher the pressure I'd be able to put into the better, although I am not really concerned as I dont particually have anything in mind. I'd probably like to be able to heat it up a bit - if the reaction required so - so something made of metal would be ideal. I dont mind if it is more theoretical than practical information but I would preffer practical, say something that I could do at home [regardless of its difficulty]. Any ideas are welcome, Thanks!
