How can i colour grains of sand?

Question

So i can fill hourglasses with different colour sands.

Answer 1

Well you can buy different colors of sand (that's what I would do), or you could do this:

Materials
sand
a clear jar with lid
plastic cups (not foam cups)
paper towels
powdered fabric dyes or food coloring

Instructions:
Set out as many plastic cups as you want colors of sand, and fill each cup half full of sand. In another cup, mix water and as much dye powder or drops of food coloring as it takes to make the color you want. Remember the dyed sand will be lighter than the colored water, so go a shade or two darker. Pour colored water into the cup of sand and stir with a plastic spoon. Rinse the water cup before repeating the coloring process with each new color of sand. When all cups of sand have dye in them, let them stand at least 15 minutes.
Carefully drain the water off of sand. (It's better to go this outside sot hat no grains of sand will go down the drain.) Cover a worktable or countertop with waxed paper; then lay out four sheets of paper towel (4 thicknesses) for each color of sand. Spoon the sand onto paper towels, spread it out a bit, and let it dry. Keep colors separate. After the sand is dry, carefully begin to spoon it into dry jars in beautiful layers. You can make "mountains" and "valleys" by mounding sand of one color against the side of the jar, filling in the valleys with another color.
