Growing Borax Crystal Oranments

By: Dakota

Question

Question

Does leaving borax and pipe cleaners in water for longer periods of time make bigger crystals?

Hypothesis

If I leave two pipe cleaners in a cup with cooled borax and hot water, than the one that I leave in for a longer period of time will form bigger crystals, because the borax will have more time to form with the water and connect to the pipe cleaners.

Chemical Reactions

  • Systhesis.

  • Endothermic: The reaction is accompanied by or requiring the absorption of heat.

Steps

Procedure

1. Heat 3 cups of water up to boiling point.

2. Pour that boiling water in your jar.

3. Pour in 4 tablespoons of borax for every cup of water, or pour some in until they water and borax wont mix anymore.

4. Shape you pipe cleaners into whatever shape you want, just make sure its small enough to fit in and out of your jar.

5. Color is also really important, dont just pick a random pipe cleaner color, as when the crystals grow, they will be mostly clear, so all the color you get will come from the pipe cleaner.

6. Tie your pipe cleaner to a wind splint/pencil using some string.

7. Put your pipe cleaner in the jar and make sure it's completely covered and not touching any of the sides or the bottom.

8.Leave it to rest and do not move it and touch it at all until you want to take it out.
