Salt crystals

Experiment from Ania & Asia


Needs:
- water
- salt
- a glass or jar
- some tool (we used spoon)


Prepare saturated solution of salt water. Try to mix as much salt in wateras is possible. Put the tool into the glass. (You can also attach a piece of woollen yarn in the middle of the little stick). Put the glass in a warm place for a couple of weeks.

Observe the appearance of salt crystals. The grown crystals are in the shape of cuboids with shiny and smooth sides.
