Sheesh. He couldn't have whacked the weeds?

Sometimes, in the heat of battle, with the sounds of thunderous engines approaching, one simply forgets - no excuses!, but one simply gets distracted and forgets - to remove one's pole pruner from the truck and, holding it horizontally, clip the disgusting leaf fragments emerging from the muck and the water.
Lighten up, Joe! They are only covering hoppers, after all.

Does anyone know, how are these shots done, if one has the camera in a housing that is halfway immersed in the water, does one simply have to be perfect and steady and not get any drops of water on the part of the housing above the surface?

LOL - hilarious, Joe. I agree, what a mess under there!
J - I'm sure Joe was referring to the submerged "weeds", hence the
As for water droplets - the water looks pretty calm to me.

I assume he uses one of those watertight housings, or at least some plexiglas box of some kind.

I understand that a housing/box of some sort is used. My question is about the details. So, say one has the housing, and by mistake one dips it two inches too deep. As a result there is a film of water covering the box in front of the lens. Most of that water will run down, of course, but there will generally speaking be some left, some drops. One can perhaps spray the surface with some sort of chemical so the water completely sheets off. Or one does something else. Or it is essential to be super careful not to overdip. I am wondering how all that works in practice.

He probably used a tripod (an old one, perhaps) and took extra care to not splash around the water when he put the camera in the water and pressed the shutter (or used a cable release).

Incidentally, that ShamWow is made in Germany so you know it has to be good.

An Aquarium would work without water in it.

Wouldn't there be a hard edge from sticking something in the water. I thought the water was so clear that all you had to do is hold the camera just above the water to capture a scene like this. At least that was my impression.
Here is sort of an example although I haven't tried it with trains yet.

I of course have no idea, not having tried it, but I suspect that the combination of the water not being completely still, if only due to vibration, plus the edge being out of focus because so close, plus various light refractions at the point of transition, will result in the soft edge visible in the shot.

That hard edge you're thinking of is probably being softened by the DOF being way beyond surface of the lens.

I was thinking that the greyish line was the Capillary/Adhesion Action from the glass vs water
"When an attractive force exists between two unlike materials, such as a liquid and a solid container, the attractive force is known as adhesion. Adhesion is the force that causes water to stick to the inside of a glass. If the adhesive force between the liquid and solid is greater than the cohesive force within the liquid, the liquid is said to wet the surface and the surface of the liquid near the edge of the container will curve upward"
