Answer 2

Answer:

There was no equipment to create temperature difference in the water.

Explanation:

The temperature difference would create convection currents in the water causing the water to flow from the hot area to the cold area. Thus the hot water would carry the ink with it to the cold parts of the water, causing the ink to get evenly distributed throughout the water. The lack of temperature difference is the flaw in the experiment.
