Generates synthetic physics simulation tasks involving domino chains with gaps. The task is to identify which domino will be the last to fall when the chain reaction encounters a gap that is too wide to cross.
Each sample pairs a task (first frame + prompt describing what needs to happen) with its ground truth solution (final frame showing the result + video demonstrating how to achieve it). This structure enables both model evaluation and training.

Analyze the domino chain to find which domino is the last to fall. Push the first domino and watch as each domino falls and turns red. The chain will stop when it reaches a gap that is too wide. This gap will be marked "TOO FAR!" in red. The last fallen domino will be circled in green as the answer.

Identify which domino will be the last to fall in a chain when the chain reaction is stopped by a gap that is too wide for the falling domino to reach the next one.
- Domino Chain: Linear arrangement of 7-12 dominos in side view
- Variable Spacing: Normal spacing (60-90 px) between most dominos
- Gap: One gap with excessive spacing (180-240 px) that stops the chain
- Physics Threshold: Domino can reach up to 90% of its height (126 px for 140 px tall domino)
- Visual Indicators: Gap marked "TOO FAR!" in red, last fallen domino circled in green
- Gap detection: Tests understanding of physical reach limitations in domino chains
- Physics reasoning: Requires calculating whether a falling domino can reach the next one
- Sequential simulation: Dominos fall one by one until the gap is encountered
- Visual state change: Fallen dominos turn from blue to red
- Clear answer marking: Last fallen domino is highlighted with green circle
- Explicit gap labeling: "TOO FAR!" text marks the problematic gap
- Variable chain length: 7-12 dominos create different difficulty levels
