This is a 2-minute chalk drawing before and after a spell of rain. There is a visible slanted pattern to the wash. Faint parallel lines, as though the chalk was dragged with a rake, travel down and to the left. The marks are visible to the right of the engine not hitting on all cylinders.
Those are not gravity lines. They are made by wind and rain penetrating a picket fence at an angle. The area to the far left is the most shielded from the wind and rain, so the parachute remains sort of distinct.
The wind that accompanied the rainstorm today pushed the chalk towards the bottom edge of the slate. The car is more of a blob. The air intake scoop seems lost in smoke. The driver is porridge, consumed by the plush driver seat. The red pin stripe dripped upon the ground. The front wheel sags. The back wheel is coated with blooms of chalk. The back wheel was unusually small for the purpose of rendering it within such a tight space.
The engine sits in front of the driver of the slingshot dragster. That is not a good design for stability, so it was phased out fifty years ago.
They do not build dragsters like that anymore. Of course, they still build slingshot dragsters. People dislike being on fire. They put the engine behind them, instead.
