Magic Crystal Tree Science project

Hypothesis: this is where you state whether it will work or not and why you think it will. Usually it is stated as a if, then, because sentence.

Ingredients Needed

  • Cardboard
  • Water
  • Salt
  • Bluing
  • Household ammonia
  • Food Coloring
  • Bowl
  • Scissors


Draw your design out (Most likely a tree or a mountain), Then using scissors cut out your design. A tree is a good design because you can cut slits so its a 3d structure as shown in the photo below.

Next add food coloring to your tree tips. Whatever color you would like. Just note that whatever color you put on your tips of trees that is what color the crystals will be turning when it gets to that point on the tree.

Now using the bowl, mix 1 Tbl spoon of water, salt and bluing. Then add 1/2 Tbl spoon of the household ammonia to the mixture and mix. It should turn into a bluish color.

Lastly put your tree into the mixture and watch it come to life. It should take about an hour to grow and start to see crystals, but wait over night to see it fully grow.


The cardboard tree uses capillary action process to draw the magic solution up its entire shape until the cardboard has soaked itself in the solution. The solution then evaporates, and is sped up by the ammonia. As it starts to evaporates off the tree crystals are left behind on the branches of the tree.As the bluing and salt water make their way up the tree, the water begins evaporating. These means there is less water able to support the bluing particles and dissolved salt. This evaporation allows the salt and bluing particles to crystallize, resulting in your beautiful tree.
