First pick up the glass block in front of you and put it in front of the glass box. Then grab the next glass block and walk on top of the glass box and put the block on the END of the glass box. Pick up the last glass block and walk to the end of the glass box on top of the glass block. You should be 3 spaces higher up then you were from the start. Turn to the left and drop the glass block. You should drop down right next to the goal. Its quite easy to get to the goal in 11 seconds.
