I too once had to make this project and my Chem. teacher suggested my class to check out the vids on Youtube. I did but I still could not understand it.But when she suggested some ideas,I actually understood what she really meant in giving the project, She wanted us to understand it by doing it ourselves.
If you still have ANY sort of problems or IF you feel like I did something wrong, then just type it down in the comments, and i'll see to it. Do comment. I do not owe the music, but the animation part is mine.
(Sorry for the stupid quality video, i could not convert the video that I actually took previously "-_- so i shot the video from the computer, sorry about that)
