You know how if you peel a sticker off your window it leaves a spot that never gets foggy? Well why don't they just sell big stickers you can put on your window and then peel off. It would fix window fog forever. Plus imagine selling that" like yea they just throw them away when they are done, then people would start throwing them into creeks and ponds and animals would catch themselves in them. This would do wonders for the fresh fish industry however because the fish would come prewrapped and people would just have to skim them up off the water with big nets and hooks. Then to solve hunger in India we could just throw a bunch of window sticker spots into the ocean! Tuen I would build a submarine and to the moon I would go. That would be so fun to invent and do.
