80's kids movie. Brother & Sister telepathic.
Hi. I'm going crazy trying to find the title of a movie I had seen when I was a kid I think it was from the 80's. All I remember is a boy and girl, brother/sister they looked like they must have been 11 or 12, and they had telepathic powers which they used to talk to each other and to move things. I think in one scene the girl is playing a flute telepathically. I also vaguely recall the two of them getting on a spaceship and leaving earth at the end. Thanks in advance.
