Ink is spreaded faster.
The way invisible ink works depends on the method used to make it.
If the eluent is above the 1.5cm line in a chromatography experiment there will not be a proper distribution in a test tube to discover the sources of ink on a paper. A chromatography experiment tests for the sources of ink whether it be chemical or plant based.
The reason a drop of ink will spread over blotting paper capillary action.
The molecules in the drop of ink will diffuse through the entire beaker of water. This will result in a homogeneous solution because of diffusion. This will only happen if the ink is of similar density to water.
What are the dependent and the independent variables in the invisible ink experiment ie To identify the best invisible ink experiment.
Ink is spreaded faster.
Evaporate the water, leaving the ink behind.

Yes. There are no ink pools and it doesn't drop from trees!

You should try it and see. Go to the kitchen, get a clear glass of water, and add a drop of food colouring to it. Or ink, if you have it. It's probably how quick the ink spreads through the water
Capillary action causes it to spread.
The red and green inks are uniformly distributed throughout the pan.

If the blue ink is the kind you use in your desktop printer, the ink will diffuse faster. The kind of ink they use to print newspapers will never diffuse.
