I realized I had some rice in my cabinet. I don't usually buy rice, so I know this is out. I decided to dye it different colors.
I am planning to make different colors for each bottle. I am not sure what all I plan to put in each one, but I can add things to it after school starts. Maybe I will do one per theme if I have little things to put in the bottle.
So far, I have made red, blue, green, and purple.
I put the rice in a bowl, added food coloring, and two "lid fulls" of rubbing alcohol. It seems like the rubbing alcohol activates the food coloring and makes it brighter.
