overnight.
not very long
it only takes about 1 day
It depends on how much food coloring you are trying to absorb, and how big the celery is. If you have a small stick of celery and a lot of food coloring, it will most likely take about a week or so for the celery to completely absorb the food coloring. When the color of the water and the color of the celery switch places, it is fully absorbed. I will be doing this experiment myself to see how long in days, minutes, and seconds it takes, but if you have any more questions, try it!
add food coloring any color you want but not to much it will take the taste out of the icing
Well i say water because food coloring probably doesn't have as much water in it.
Take a milkshake and put 3 drops of red food coloring and 3 drops of blue food coloring! :)
it takes about "i-don't-know-how-long" for a rose to become a rose.
Well I hope they way your doing it is to put Blue food coloring in the water and wait a few days and the rose should become blue if not put more in or ask a flower shop keeper
If you want to get the answer, you should do the experiment instead of going on Google to find the answer!
It depends on temperature. The warmer the liquid the faster diffusion occurs.
nothing color is in water for ever
It takes about a day for colour to start to show up, assuming you do the experiment right.
