1.  Fill the bottle three fourths (3/4) of the way with vegetable oil.

2.  Fill the rest of the bottle with coloured water.

3.  Close the lid tightly.

4.  Turn the bottle on its side – watch as the colour moves through the oil in funny shapes and blobs.

The water and the oil do not mix because the water has more density than the oil.
