hey, we did this in 6th grade science class! but there is something you can do to mess it up, it's very simple but i cant remember what it is. i've also done this with my nieces. fun for kids with a little patience
I had my niece and nephews over and we decided to try out hand at making this. The kids had fun mixing the colors and I had fun showing them what to do. They each went home with a baggie full of candy. I thought their mothers were going to kill me for making them all sugar candy, but I look at it like this...It was something memorable for us all to do together and we all had fun!
This was tasty and easy to do, though I moved the string too soon and it didn't come out of the heat-proof canning jars I used. I then had to chip it all out to get at the candy. The next batch I made I used flat, greased pans. Then as it cooled, I poured it onto wax paper. They didn't make long chunks of candy but individual crystals. That was fine with me because I was looking for a space rock kind of looking candy and that's what I got. I also colored the candy with food coloring for a cool effect. Neato!
