this simple project looks great requires little maintenance.
It can be completely modified for just about any materials you have.
Step 1: Materials
-small bottle or similar container (shorter and fatter the better)
-assorted tubes, test tubes, etc.
-seeds, (lentils or alfalfa grow really fast!!)
-drill or hole poking device
-knife of some sort
-glue? is that a material or a tool?
