Quick cactus drying

[Dr. Awesome]

Swim is planning on buying a bunch of cactus when his parents go out of town in a few weeks. He's planning on doing an alcohol extraction and figures that the 8 days he has the house to himself should be enough time get it done, the only problem though is that he lives in the US and as far as he knows he cant buy dryed cactus so he needs to dry it out fast so there is plenty of time for it to soak in the alcohol.

This swim has been thinking of slicing it up into thin slices and either letting it sit in the oven at a low temp or setting it out in the sun or something. Swim would appriciate any advice
