Amazing Alex The Backyard level 2-21, called “Underwater Adventure”, is rather challenging. Place the 8-ball in the slingshot. Angle a shelf slightly upward just left of the second balloon, and place the scissors just above the balloons on the extreme right. Place one more balloon just left of the bottom star. Hopefully everything goes well and the cardboard box actually reaches the ground.
If you have a different strategy for completing this level feel free to leave a comment below.
i put the wood above the four balloons and placed it almost exactly diaginal(put the left side below the right) then placed the scissors pointing at the balloon(on the side with four balloon) that was the second most highest, and then put the 8 ball in the slingshot, then played for 3 stars
