Pour the crystals in the water when you put the eggs to boil. Boil for 10 min. after boiling point.
Dissolve the dyes in bowls, adding a little vinegar to each.
Leave the eggs to cool in the water after they're done, that way the crystals stick to the eggs.
Once cooled, take them out and dip in the dyes. To make them more colorful, dip each egg in all of the dyes.
