Trevin wanted to grow crystals in different liquids for his science fair project. He used 10 different liquids and did salt and sugar mixtures. The 10 liquids he used were: Water, vinegar, club soda, bleach, Shasta, Coke, white grape juice, apple juice, lemonade, and Koolaid.
By day 3, the water, club soda and vinegar were all growing crystals. The bleach/salt mixture ate through the string, disentegrated the paperclip holding the string down and started forming crystals on the surface of the liquid.
By day 7, he still only had crystals forming on the strings of vinegar, water, and club soda and all 3 of them were doing really well.
By day 14, he had crystals forming on the salt/apple juice mixture and his first sugar crystals were forming on of all things, the sugar/bleach mixture.
By day 16, he started getting crystals on the Coke/salt, and Shasta/salt mixtures and the apple juice/salt mixture was getting a few more crystals. The Coke and Shasta mixtures were growing crystals on the string as well as coming towards the center from the edge of the cup.
By day 21, all of the salt mixtures had crystals forming and growing. They were all growing in different shapes though, nothing consistent.
Although vinegar/salt was the first to appear, the water/salt crystals that formed were the bestlooking crystals.
This is Trevin with his display board. He seemed to have fun. I'm grateful to have my kitchen counter back.
