Colloidal gold

Colloidal gold is tiny bits of gold suspended in a liquid. It is made when gold is dissolved in a special solution that doesn't allow it to stay dissolved very long. The gold forms tiny flakes, or particles, that stay suspended in the liquid. These tiny gold particles stay suspended in the liquid because they are so light and small. Colloidal gold is often used in products like creams, shampoos, and medicines, because it has lots of special healing and beauty benefits!
