I found 2 cluster of snail eggs hanging on the underside of my 40g tank and wondering what happens when they hatch. Will just just fall into the water or Will they make their way down the side and into the water?

Best I can figure the babies are full functioning snails, and will just move away like any old snail.
I haven’t actually watched them hatch to confirm.

I assume these are either apple snails (Ampullariidae) or 'mystery snails' (Viviparidae), as these are the types commonly placing egg masses outside the water.
In either case, as eggs hatch, the mucus/fluid contained in each egg, usually forms a droplet that falls into the water, carrying each tiny snail. The whole mass may hatch within a day or two, although sometimes part of the egg mass does not contain viable eggs. Most baby snails don't need to crawl into the water but some might.

So if they do fall into the water then could I put a net or something under the eggs so that they don’t get eaten by tetras as they fall? If I can do that then could I also keep them In that net or move to a plastic container until they get a bit bigger.
