How to get three stars in angry birds space wold 2 level 22
Another three golden stars is within your grasp. All you need to do is fire the one bird as seen in the screenshot above. As it reaches the first chain press down and make it blow up. This will make the upper pig blow totally of the grid and also it will push the collection of rocks into the big planets gravitational pull. The pigs will all be wiped out as they hit the surface and give you enough pints to get you what you want.
A video guide of the whole thing can be seen below:
