The “Crystal Workshop” set will allow children to create an unusual toy and observe the process of crystal formation.

In the set

  • wand for mixing.
  • Measured spoon.
  • measured glass.
  • gypsum.
  • Powder for growing crystals (2 colors).
  • disposable gloves.
  • mold for 4 figures.
  • jar.
  • spit.

how to do?

  • pour In a measured glass of gypsum to the mark of 40 ml, then colored powder - to the mark of 60 ml. Mix the powders thoroughly with a stick.
  • pour 20 ml of warm water and mix well until completely dissolved.
  • fill the molds with the resulting solution and leave them until completely harden (for about 12 hours).
  • After that, take out the figures from the mold and take them into the refrigerator for 3 hours.
  • When the cooling time of the figures comes to an end, prepare the solution in a special jar. Mix 100 ml of water immediately after boiling and half a bag of powder for crystals (the same color that was added to the gypsum figure).
  • thoroughly stir the solution until completely dissolved for 2 minutes.
  • Immediately after preparing the solution, take out one figure from the refrigerator and place it in a jar of the solution. Important! In one jar can only be one figure, so either do in turn (the remaining gypsum figures can still lie in the refrigerator further), or take a similar container and prepare a solution for the rest of the figures.
  • check the figures through 4 hours, they will already have crystals. Wait a few more hours and carefully remove the figures from the solution.
