it only takes about 1 day
No as long as the coloring agent is not toxic but it can affect the color of a flower that has been cut.
Food coloring doesn't expire so you can keep it on the shelf FOREVER :D
not very long
Yes as long as its not crunchy cause the peanuts wont be good with food coloring
Physical, the water is still water and the food coloring is still food coloring you just mixed them together in one space. If you waited long enough the food coloring and water would settle back out so you had just water and food coloring.
overnight.
Yes it can, however, it shouldn't last long.
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!
"how long is piece of string?" depending on the color, because there is so many different types of food coloring there is an assortments of different ways which they are made some food coloring is made of chemicals and some is made of organic substances even bugs.due to the question being so open/indirect, there 10's of different answers on the ways of which food coloring is made, green food coloring is often derived from seaweed, colors in jelly's are often chemical and hence commercially produced in a big factory.
Food dyes are typically not harmful to plants at normal concentrations used for science experiments or coloring. In most cases, the dye may be absorbed by the plant and may even change the color of the plant's tissues temporarily, but it should not result in the death of the plant. However, using excessive amounts of food dye or certain chemicals in the dyes could potentially harm the plant.
When the container with food coloring is placed above another container, gravity causes the food coloring to flow downward. As it descends, it may mix with any liquid below, creating a diffusion effect that spreads the color throughout the lower container. The rate of mixing depends on factors like the viscosity of the liquid and the temperature. Eventually, the food coloring will evenly distribute in the liquid, depending on how long it is allowed to settle.
depends what type of plant you are
