Some years ago, I watched a series on Swedish television. I remember the show was NOT Swedish, but from the UK (maybe USA?).
I only remember one episode specifically and I can't get it out of my head.
It was a show about kids/teens and science. The episode I remember has a science person (not sure if it was a teen or adult) create a machine that can suck peoples' brains out with a tube and launch the brain (in this case, into an aquarium).
I remember it showing two perspectives. One perspective was from two brains that got launched and somehow ended up outside. They could talk and move (by bouncing around), and it was a girl and a boy. The other perspective was the science person using their bodies and turning them into remote controlled people through special hats.
I remember it ending with the a show and tell, where two kids had used the machine on their friend and put his brain in a jar and they showed the remote controlled body as a presentation.
