STEP TWO: place one graham cracker in the plastic bag and crush it until there are no big pieces left. Then put these into the bottom of the cup.


This is the parent material or “C layer”.IMG_3872 STEP THREE: Empty one full pudding cup on top of the graham cracker layer.IMG_3873

This is the subsoil, or “B layer”.

STEP FIVE: Place a few Oreos into the other plastic bag and crush until crumbled. Then sprinkle this on top of the whipped cream layer.


This is the organic layer. It is made up  of the matter that was once living.
