How to smoke oxy’s? (high tolerance)

So I’ve been railing pressed oxy’s for a few months now and wanna try a new method of consumption. How exactly do you smoke them and how does the high compare to railing them? I’m looking for a simple method and obviously want to avoid being wasteful of my limited stash. Heard about like the tinfoil method but instructions were unclear and I feel like I’d fuck it up, any advice on most efficient and effective way to smoke them? Detailed guide would be incredible. Is it even worth it, is the high different at all? Also, in your experiences what is truly the method that will get me the most fucked up? (Aside from IV bc fuck that)
