As shown, the materials are all items found in a non-kite-builders home. Planter flats from a flower purchase, gardens stakes, tall plastic trash bags. The flats are held together with tape and bound around the outside with bamboo plant stakes tied at the corners and hot glued to the plastic "sail". The plastic bags are fused into a banner tail with an iron between layers of kitchen parchment paper. It is bridled like a Rokkaku.
It was gusty today and I could get it to momentarily lift, but it would need a stiffer breeze. (Full disclosure: the last time there was a beach wind in Missouri, the air was blowing off the glaciation of Iowa.) Still, I posit that it flies.
