Glass jar (Mason jar works well)

Water

Food coloring / bio colors

Vegetable oil

Salt

 

~~Pour about 3” inches water into the jar

~~Add coloring (keep colors light)

~~Slowly pour 1/3 cup vegetable oil into jar

~~Waite until both layers have settled

 

*Hint

The oil will sit on top of the water

 

~~Gently shake salt into jar and count to 5

~~AS you watch the oil and salt will form a “blob” and sink to the bottom of the jar

~~Keep watching as the “Blob” floats back to the top of the water

~~Repeat by shaking more salt into the jar

 

Ask the children why the oil “blob” sank to the bottom and then floated back to the top?

 

Oil is lighter than water which is why it sits on top of it and since oil does not dissolve it won’t mix with water.

 

Salt is heavier than water and it also dissolves in water so When you shake it onto the oil, it clings to the oil “blob” and brings it to the bottom.

After the salt has had time to dissolve it releases the oil “blob” and it floats to the top.
