They are, but it uses a very rare rescource, so it is then shut down.
I wish to heal from this terrible sickness named "the common cold" while becoming immune to all other sicknesses.
Sicknesses help you become stronger (if you survive), so become immune to all 'Known' sicknesses but a new one comes up and you have no immune sytem build up to fight it.
i wish for a lot of bubblewrap
Because of that, everyone is forced to carry a paperweight everywhere they go. Thanks a lot.
I wish forthe U.S. to get out of it's huge debt.
however, after the US cured from his huge debt, someone steals every money in almost every bank, thus making a worse, new debt.
i wish i have a save box filled by quartz sand, the sand is save, cannot be stolen, not by stealing, is very many while still fits in the box, the box is light and small, without any kind of weaponry/trap inside,can be used to make glass, outside my house while im in my house and not teleportable/warpable to my body.
However, you do not have the equipment to create glass with it. Additionally, the people who make save-boxes-filled-with-quartz-sand are very angry at you for not having paid for it, and they're threatening to take you to court. As you are already bankrupted by the extravagant shipping fees, you're pretty much screwed.
I wish for...potato.
(I also wish people knew how to English on this thread...)
granted. a giant, heavy potato falls from your home's roof, causing you crushed to death.
i wish i had a light, small potato. (granted, @Feynmanlogomaker?)
Granted. A small, light potato flies at you at the speed of light and causes your body to fuse and explode.
I wish the next user posted.
I post, but not because you wished it.
I wish for there to be no such behavior as "trolling"
