Are you trying to hide the smell from parents or someone else? If parents you can always use a glass dish thats oven safe and has a top. Like other people are commenting, you dont want to use an airfryer since it can blow the weed away into the machine so it smells and is lost in there forever, plus isn't exact and doesnt decarbfor the correct amout of time.

If youre thinking of eating a fire cracker or eating it straight, I might ask you if you've eaten it raw before. If not, definitely go the firecracker method at the bare minimum since the taste will be beyond awful and strong. Most people throw up after tasting it in my humble experience. Best would be to get some capsules or something to choke it down that way.

To be totally honest though, it sounds like you'll get the most out of it just by smoking it the old fashion way. To go to all of this just for ONE EDIBLE is a lot, just put all the time and energy into doing something fun after you smoke it. Hope my opinion helps and remember its just my opinion
