Food Coloring

At a grocery store.

No, it is not. It completely dissolves. If you want to check if a mixture is a colloid shine a beam of light through it. (A flashlight should work, although a laser pointer is best. If you're having trouble getting a thinnish beam with your flashlight take a piece of cardboard or some other opaque material and cut a hole in it. Then shine the flashlight through that.) If you can see the beam of light the mixture is a colloid. Pure water, for example, is not a colloid. I have found that flour and water makes a very nice colloid. Smoke, fog/mist, clouds and honey are some naturally occurring colloids.

I wouldnt think so

A drop at a time while mixing to achieve desired result. It only takes a little, it is surprisingly strong.

Ahhh no.

Popular coloring pictures are animated characters. It is popular because the characters catch children's attention and attract their eyes, which will make them want to color it.

The short answer is "no", but it depends on the bird. The colour of canaries is influenced by the food they eat. For example, foods rich in beta-carotene (such as berries, tomato, sweet potato and carrots) are necessary for a red factor canary to maintain its colour. Colour supplements can be detrimental to the health of canaries, and other birds. As for 'Pre-coloring' domesticated foul, such as Chickens, you must inject dye into the egg before birth. This procedure is now illegal in most states in the US, as it can kill the young birds at a very early stage in life, so in other words it is extremely detrimental to their health.

Food coloring in anything is generally "bad" for you. Whether you have too much is the question. The red dye in products such as Hot Cheetos can be the cause of a certain cancer. Just because the food coloring may/may not affect you, doesn't mean that the drink isn't safe. Though, Hawaiian Punch in almost completely Artificial, so the chemicals you are taking in are in fact unhealthy. I recommend juices such as Welch's, Ocean Spray, and V8. Hawaiin Punch is a lovely drink to take in only at snack time. (:

Yes, absolutely, in fact it is very good for their immune systems. I am a doctor, and this may be surprising but food coloring is very beneficial for their health.

"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.
