Sparkling Star Dip

-Making crystals is a beautiful way to remove a solute from a solution.

You'll need:
pipe cleaners

1) Ask a grown-up to help you fill a far with hot water (Boiling water is best so use caution) Add Borax, 1 tablespoon (15ml) at a time until no more will dissolve. (This will be about 3 tablespoons (45ml) per cup (250ml) of hot water used.)
2) Make a star shape with pipe cleaners; then attach a string to the shape. Place the star in the solution. Let it remain overnight.
3) The next morning, lift out the star by the string. Enjoy the sparkling results.

You can also do the experiment using Epsom salts. You'll need about twice as much Epsom salts as water.

Compare the shape of the Borax crystals with the Epsom salt crystals.
