This project was converted from "Snap!" into Scratch. Original project by codechespin: https://snap.berkeley.edu/project?user=codechespin&project=Ball%20Physics%20v1.0 The only thing really different is the 60FPS and the stop sign. If you want to play in 60FPS, then try the Scratch Addons extension and use the 60FPS feature by Alt+Clicking the green flag. Same thing for the stop sign.
