Does color flow taste good because it smells bad? I am also afraid of it because my instructor says it will give you diahrea if you taste it while it is soft. So does it do the same when it hardens? I don't want kids to eat it at a party and get sick???

I don't know why it would have any negative effect if you eat it while it is still wet. (Makes no sense to me, to be honest.)

It tastes pretty bad if you make it according to the recipe on the can, and it is quite hard. On the other hand, when I flavored it with some clear vanilla, kids gobbled it up. I made little dots on parchment with the leftover, and several people said it reminded them of a candy they had eaten as a child.

I have used color flow on a couple of cakes as buildings and I used lollipop sticks to hold them up right. Well anyway once the kids saw buildings on sticks of course they wanted to eat them... Everyone was fine. The taste is not bad, but not good either just really hard sugar!
