Chemistry At Its Finest by natattack-alex Chemistry At Its Finest by natattack-alex
So my AP Chemistry class is putting together a magic show for the Lower Schoolers (they think it's magic but it's actually just chem lol). This is my act for the show. I trapped a rainbow into a graduated cylinder. Can anyone tell me the chemistry behind this trick? I'll give you a llama if you can! :D

Answer: Here's what I did. Each solution has a different density but they are all made up of the same solution. Here's the trick. The red color is the least dense because it is 100% water. The orange has 10% sugar in it. As you go up the color spectrum you increase the amount of sugar by 10%. So Yellow: 20%, Green: 30%, Blue: 40%, Indigo: 50%, and Violet: 60%. Because the mass/volume ratio increases so does the density. Yay chemistry! :hooray:
:llama:
**Everyone that answered gets a llama!! :thumbsup:

density=mass/volume
mass=density x volume
and
volume=mass/density
