How do i dye my blonde hair black for one day?

So there's this project at school where i have to dress in the exact opposite of myself, so i want to dye my dirty/strawberry blonde hair black...like changing my race from white to asian with the darker hair. BUT i do not want to go permanent, i LOVE my blonde hair. What can i use for a one-day-use to dye my hair black?

because i really don't want black hair for ever...i like my blonde, but i just want black for one day. but if it works for like 3, that's ok too. just as long as it's not like, a week.

thanks!

DONT do it. My mother has a hair salon and is very experience. Even the temp color can be a disaster. WEAR A WIG! That perfect blonde is so hard to get, don't mess with it.

You can try using a temporary hair color, but it might take some time to wash out. They usually last for 6 - 10 shampoos.

Since your hair is blonde and you want to go black, do not use any temporary hair color, hairspray, gel, etc. Black is so concentrated that you might not get your blonde back for awhile and it could be a disaster. So your best bet is to get a wig!!
