I had to learn physics once to graduate high school. I ended up applying what I knew to form this small environment where you could launch little rockets in real time, then completely forgot everything. A good time waster if all you do is go on Newgrounds all day. 

Instructions: Click once, then move around your mouse to change the magnitude and angle of the rocket. Click again to launch.

You guys are still having fun online without me right?
