Level 3 in Physics Drop is quit tricky for this early stage of the game, and most of the people playing the game will give up. Fear not, there's a simple way to pass it. Just make a line from where the ball is, to the "U" shape. Now draw a small line, FAST, into the red ball. This will launch the ball with high speed and it will easily reach the "U" shape. See the video below for more details.
