Roto animation

Ive been trying to learn animation for quite some time. In class we learned a technique called rotoscoping, this was tracing frames to produce a animation. this for me was a no brainer in that i have been practicing drawing frames on paper then retracing them in the computer to get a decent animation. Our assignment was to portray one of 4 instances. show something falling, breaking, water spilling and i cant remember the last one. I tried to go for all 4 in one shot. It took me about 1 hour to get this final product minus the separate soundtrack i made. Enjoy
