Experiment about the mixtures.

Today we did some experiments about mixture.
 We bought: salt,oil,sand,vinager,tea and water.
We mixed  water with salt, and vinager. They are homogenius mixtures because we can not distinguish their componets.
We mixed water with sand, with oil and with tea herbs. They are heterogenius mixtures because we can distinguish their components.
Then we separated some of the mixtures by filtration, decantation or even evaporation.
 We observed that the oil fleets in the water.
The experiment  was very funny!
