Why can an airplane fly with wings made of water?

mulllBymulll

This new viral video shows how to build a flying model airplane using a 3D printer and water/dish soap. The wings are practically liquid, but why doesn't air flow through them?

I saw a video on BBC about the video, but I couldn't understand it because it was in English.

Aircraft fly because the wings move against the air and thereby generate lift.

In the video, the supporting surfaces are replaced by soap water, which is kept smooth by the surface tension.

This is exactly the same principle as an aircraft

You know soap bubbles. They're flying too. It's the same principle.

The wings are closed and the shimmering veil of soap water remains.

The total weight is low enough that the enrichment force cannot act strong enough.
