Each month a kiwi crate shows up. This gives RJ some quality time with Granddad where he can put the contraption together.
This month was an experiment on osmosis, cohesion, or tension ... or something like that that causes water to move up the roots of plants. This experiment allowed us to witness the colored water getting pulled up 'plant stems' to add color to paper flowers. We never explained why the yellow dye moved faster than the red dye.
