Drag the bird back on the slingshot, aim, and let go. Smash the blocks and pop every core. Wood breaks easily, ice shatters, stone takes a real hit.

The dotted guide is the parabola y = x tanθ − gx²/(2v²cos²θ). A faster launch carries more kinetic energy (½mv²), which is why a full stretch breaks stone and a gentle lob only nudges it.
