I drop a drop of water on the table, blow it with air, and the water will move with the wind. Why is there no trace of water in the passing place?

What you are trying is probably a material that does not touch water.

Besides, did it blow too hard and blow away most of the water? There is only a thin layer, which is easy to evaporate when blowing hard. You can blow it with salt water or muddy water with impurities to see if there are any water stains. If it evaporates, there should be water stains.
