Crystals

Crystals lab
In september we did lab about crystals. We grow crystal by using hot water, minerals, some science cups. We mixed and mixed water with minerals (adding 2 spoon minerals) till it cant take any more minerals in it. also we add food paint in it. Then after that we put our water mineral on window with open window to cool it down. After many days it grow a lot and turned to crystal.... JUst like this..
