Crystal Farming pt 2

Growth seems to be slowing down on the borax string, but there is heavy crystal growth on the jar itself. The baking soda string is still showing slow signs of growth, but definitely still growing. Our sugar, salt, and washing soda have no change at this time.


Crystal Farming pt 1

We start the project off with 5 beautifully colored jars of boiling water, each with a different mineral that should produce crystals at varying times. We have washing soda, sugar, salt, baking soda, and borax.

Within one hour we have seen some growth. The borax has started producing cubical crystals on our yarn.

With the growth doubling again at the 2 hour mark.

Also at the 2 hour mark our baking soda has started forming spike-like crystals. I personally did not expect the baking soda to produce any crystals because it appeared that the food coloring had a chemical reaction with the baking soda before the baking soda all seemed to gather at the bottom of our jar.

But seriously...watching crystals grow is much like watching paint dry...I'm so glad that we have 10 days before his science fair project is due! Plenty of time to have some great growth!!! Now if only we could get the water to evaporate quicker! LOL
