DIY mineral and crystal experiment

Join science student Erika as she demonstrates how to grow crystals from borax. Naturally occurring borax is usually colourless, but appears white when powdered and consists of tiny soluble crystals. The soft crystals dissolve in warm water, but as the solution begins to cool they will recrystallise, growing larger as they take on more and more molecules. To start your own glittery collection, you will need borax, pipe cleaners, string, a pencil and food colouring.
