The way invisible ink works depends on the method used to make it.
Oh, dude, like, the drop of ink will totally spread faster because ink is all like, "I'm in a hurry to get everywhere," while honey is just chillin' like, "I'll get there eventually, no rush." So, yeah, ink for the win in the speedy spreading competition in water.
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.
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.
Evaporate the water, leaving the ink behind.
Yes. There are no ink pools and it doesn't drop from trees!

Zoe's experiment may not work because waterproof markers are designed to be resistant to water. The ink in waterproof markers is designed to be insoluble in water, which may prevent the ink components from separating in the chromatography experiment. She would need to use a solvent that can break down the ink in the markers to successfully perform a chromatography experiment.
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

When you drop ink onto a cloth, the ink will spread out and be absorbed by the fibers of the fabric. The extent of the spreading will depend on the absorbency of the cloth. Quick action to blot and rinse the ink stain can help minimize its spread and make it easier to remove.
Well, honey, in an invisible ink experiment, the dependent variable is the thing you're measuring to see if it changes as a result of the invisible ink being used. So, it could be something like the visibility of the message under different conditions. Just remember, the dependent variable is the one that's dependent on the independent variable - it's like the sidekick to the main character in a cheesy detective show.
The red and green inks are uniformly distributed throughout the pan.
The reason a drop of ink will spread over blotting paper capillary action.
When an ink drop is placed on blotting paper, the paper absorbs the liquid due to its porous nature. The capillary action of the paper pulls the ink into its fibers, causing it to spread and create a larger, more diffuse shape. This spreading occurs because the ink is drawn along the paper's fibers by surface tension and absorbency.
