CRYSTAL NAME 

Materials:
  1.  Pipe cleaners
  2.  Fishing line {rope or thread will also works
  3. Pencils or wooden skewers
  4. scissors
  5. Lenses or plastic container lenses {one for each color}
  6. A container large enough to hold its name {if making its name as a single piece written in italics}
  7. Borax
  8. Food coloring {optional, if you want colored letters you can dye the borax solution or use colored tube cleaners}
  9. Measuring cup
  10. Tablespoon.
  11. Heat-safe mixing vessel.
SCIENTIFIC PROCEDURE

When borax is dissolved in water a suspension is created. A suspension is a mixture having solid particles (the borax) that are large enough for sedimentation. As the borax begins to settle, it begins to crystallize on all surfaces that come into contact with the tube - including cleaner cards. As the borax continues to sediment, crystals accumulate on top of other borax crystals creating a thick layer.




PROCESS
  1.  Doing the measurement and mixing should make sure the water is as hot as possible to help dissolve the borax quickly, without being hot enough to burn.
  2. We set plastic containers of 5-quart size and had a measure out 3 tablespoons borax per cup of hot water we used {9} tablespoons per container.
  3. Choose the figure or the set you want to perform, for example a letter or a figure.
  4. Once the whole borax was measured I poured 3 cups of almost boiling water into each of the 5 containers. A, armed with a long wooden spoon, mixed each container until the dissolved borax.
  5. Add a few drops of food coloring to each container and carefully lowered each letter into the color of choice.
  6. Put the containers on a shelf and let it sit during the night when you will not be affected by the curious hands.
  7. It was difficult to see what was happening to the pipe cleaners through the dark colored food solution.


The end result would be something like this
