A spell will not give you a tail. Magic spells are not real and people can not change into things or mermaids. None of it is real and it is all make believe. If you want to pretend to be a mermaid go buy a costume.
Forever unless you delete them
Well... it will last forever but the only way to make it stop is finding the person who did it to you and reverse it on them. It will last as long as you believe in such nonsense

There are no spells to turn humans into mermaids or anything else. Mermaids and spells are things of fiction and nothing more.
Only the Pacific Ocean.
Only Forever was created in 1940.
You can't force it. You either match each other and struggle together or it does not work. There is no miracle potion or spell. Only time will tell and you can only hope he feels the same.
No spell will make you a mermaid. Mermaids are not real and are only in movies, games, books and TV shows. People can not change into other things or mermaids. It is physically impossible ( think how messy it would be). If you want to pretend to be a mermaid go buy a costume.
The turning water into rum spell was only ever featured in the movie, and was probably not actually a real spell. Seamus Finnigan is seen trying to do this and he blows himself up. The spell he uses is "eye of rabbit, harp string hum, turn this water into rum."
we never touch anyone so lightly that we do not leave a trace.
dust, water, shock, pressure, static, try to touch only the edges.
Not forever but for a long time! There is no wind, air, or water on the moon, so the only thing that will disturb a footprint will be a meteor strike or further human activity.
