Hi, I need help, I try to remember more about this movie I saw a lot years ago.
I remember there were some kids making some experiments in their house with tomatoes, they had a machine that grow up these tomatoes and one of the kids grow up whit this machine and fall in love with her teacher. The next I remember is the end of the movie when the kid shrunk to his age and they went to school and they had another teacher in the class and then a girl enter the classroom and it results to be the teacher that shrunk herself to be with the kid.

Please answer this one

Sounds like 14 Going on 30 (1988) (TV)
