More than likely.Any good prop department could build one of those.
Why fall? Why not in some other arbitrary direction?What is the driver that chooses that particular vector?It's all explained by relative density. Things float if lighter than air. Things fall if heavier than the medium (air, water).
We know by observation that lighter things float and heavier things fall or sink.Why fall? Why not in some other arbitrary direction?What is the driver that chooses that particular vector?
By the exhibit you posted, it seems that your claim is that anti-buoyancy makes the bolt want to move downward.
That observation has it's flaws.We know by observation that lighter things float and heavier things fall or sink.
