# How to keep magnesium hydroxide suspended in water?

How do I keep 8 g of $$\ce{Mg(OH)2}$$ suspended in 100 mL of water? Milk of magnesium purchased from the store has $$\ce{Mg(OH)2}$$ well suspended in the bottles. When I make it, the $$\ce{Mg(OH)2}$$ settles at the bottom of the glass within minutes.
