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! :)
The time it takes for a drop of food coloring to color a glass of still water with sugar in it depends on factors such as the amount of water, concentration of food coloring, and mixing. In general, it can take a few minutes to fully disperse and color the water evenly.
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 usually takes a few hours to a day for flowers to visibly change color when food coloring is added to the water. The speed of the color change can vary depending on the type of flower and the amount of food coloring used.
nothing color is in water for ever
