Crayon Physics - Log

The Log can be solved very easily by removing the log and then setting the ball roll. However, can anybody solve it without making the log fall? The acclaimed tunneling effect from quantum physics is required for this :) Any quantum physicists out there? can u do it?

Anyway for the rest of us the easy solution is given below. First get the log out of the way by dropping beams on top of it. Then just get the ball rolling to collect the star.


If any of you quantum physicists can do the tunneling effect without making the log fall, do let me know how u did it.
