DO NOT use a microwave to melt the pb on the cracker/s.

Microwaves work on the principal of heating the WATER in the food you want to heat. i.e. leftover spaghetti, or enchiladas.

since pb is oil based, (uh hello, BUTTER??!!) and there is no water content, or at least not enough in the crackers, your microwaves from your machine will have no where to go, and will rebound inside the machine making funky and loud sounds, bright lights, and ruining your microwave.

it could also potentially harm you, in that say, you were already high, and wanted to put ur face against the window and watch the light or sumthin, your face might melt off or sum shit. lmao
