Utopia 4-26 (Angry Birds Space)

Utopia 4-26 is the 26th level in Utopia.

Difficulty
It's hard for some to destroy all fortress with less birds.

Strategy
Fling the lazer bird down below the left cookie, then redirecting him back up through the wood plank at the bottom of the biggest structure (the wood plank to the right of the TNT). 1-birder is required to 3-star this level, so the goal is for the lazer bird to go through the wood plank so that he circles around the top right planet and takes out the far right structure’s support. This will cause the far right structure to collapse down into the bottom left structure, giving you your 1-birder.
