Filtration and Evaporation
We use filtration and evaporation to separate out a mixture of water, sand and salt. The sand is removed using filtration, as it did not dissolve in the water. The remaining solution is heated until the water evaporates, leaving behind...

Distillation of Ink
We use distillation to remove the water from ink. The ink is heated in a conical flask with a delivery tube running to a beaker. The water has a lower boiling point and so it evaporates before the ink. The water condenses as it travels...
