Build a Junk Plane lets you bolt together a flying machine out of scrap blocks, wings and rockets, then launch it straight off a cliff to see how far it goes. Every part you add changes how your plane climbs, dives and handles in the air.
It's a simple idea with a lot of trial and error built in. Crash, laugh, swap a part, and try again. You can play Build a Junk Plane online for free with no download needed.
Whether your build turns into a rocket-powered glider or a wobbly disaster, the fun is in testing what flies and what splashes. It runs right in your browser on phone, tablet or computer, so you can tinker whenever you have a few minutes.
