I did a portable soccer goal to stick it on a glass wall, to have fun and change a boring playground into a playful playground. I did the structure with cardboard and the foldable net with paper. I put suction cups to stick it correctly in the wall and velcro to hold the foldable structure when is closed. Everyone can use it, but I recommended if you like soccer. It's not only for playing soccer, it's also to have shadow.
