Cut a slot down the middle of one tree shape.
- 1 tablespoon of water
- 1 tablespoon salt
- 1 tablespoon bluing
- 1/2 tablespoon of household ammonia
The main principle at work here is capillary action. Capillary action is the same process that enables plants and trees to take water and nutrients from the soil up through their stems or trunks and into their leaves, branches, flowers, and fruit.
The cardboard tree uses the same process to draw the magic solution up through its entire shape until the cardboard has soaked itself in the solution.

After the magic solution has been drawn throughout the tree by capillary action, the solution begins to evaporate.
The evaporation process is accelerated by the ammonia, which evaporates more quickly than water. As the magic solution evaporates off of the tree, the crystals are left behind on the branches of the tree.

The magic crystals that are left behind are a combination of the Mrs. Stewart's Bluing and the table salt. The bluing is acolloid, with many tiny particles suspending themselves within the water. It's just like when you shake up a snow globe, except the particles of bluing are much smaller than the snow. These tiny suspended particles aid the dissolved salt in crystalizing as the magic solution evaporates.
