Ah! I've done the same thing with those 'kickboards' that they use for swimming lessons. Of course, you have to do it in an empty pool because it's dangerous - they go quite fast.
Ponder a Richard Feynman answer. The energy of the sun is stored in food. Man eats food and converts it to push down the float. The energy is stored as potential until the man lets go. The float rises, just like an Archimedes's bar of soap would rise when he bathed.
This particular version has 3 pounds of lift, which is supplied when you push the toy underwater, just as you would with, say, a swimboard. The shape of the toy makes the path of least resistance a forward one, such that the glide ratio is 10 to 1. The toy is remarkably flat from an end-on position. Gliding up appears to be quite different from gliding down; as far as I know, this has never been studied before.
Your Q. How does it move? I believe bornman88 is correct with how it goes. I would guess the cross section geometry of the wing is upside down in relation to an air wing. Archimedes? BC technology? hmmm.... still pondering...
ololo, fake. too fast!

Next time you're in SLC, look me up and I'll do a demo.

Was is made by you? Or it's a prototype of Aquaglider? Where can I learn more?

Oceanographers use the same idea on much larger vehicles to glide down and up and travel many km sampling the ocean

I have long thought this, but no takers so far!

The yellow bit is buoyant and it looks like the man release it about 3 or 4feet below the waterline
As the yellow wants to surface the wings resist and make it "fly" at a small angle towards the surface?
The geometry is very well calculated so it stays balanced with a small angle to the horizontal!
