I wrote this story for my 12th Grade English. What do you think of it?

Stephen Biko died September of 1977, aged 914. He died on the 14th of February. He ran two hundred kilometres to improve the stability of a floating disc that leads out into a mountain that is collapsing onto a dog inside a human sized cup of water. The water changes to a viscous goo that slowed the decent out of a hole in the cup and calmed down the masses reducing rebellion. Once the cup had drained a shadow appeared and the dogs came running home and fell off a plank leaning over the bridge. The bridge was made of soggy paper and squid, it was highly unstable but it was stuck to a tree mounted on the side of a spitfire plane. The spitfire was attached to another plane, both planes travelling at a speed of 200 kilometres per hour. The planes were moving but set in cement thirty kilometres underwater on an orbital ball rotating 200 kilometres per hour in the opposite direction. The orbital ball falls 5 units to smash a pot and kill a slug. The slug’s son avenges his father’s death by biting Stephen inside the cup. The bite then turns into a cut that is ripped open by the water pressure. The pressure then causes a pipe to explode, the steam killing the slug sitting in a lounge chair 3.43 seconds away from Sirius. The chair was triple threaded with a buff finish. The duck however was inside the chair and had no perspectives so he began to write a tale of his trip. The story was plastered across the trees inside the chair, the trees that had grown because of the moisture and lack of sunlight? Was that a question? Who knows, all I know for certain is that Grown Ups is a terrible movie.
