I first saw this movie or tv show as a child, in the late 70's or early 80's. It was shown at my public school in Canada, back in the days when the Lord's prayer was read on the PA system in the morning, so the show would now most likely be rated "Family".

The plot involved 2 children, a boy and a girl, escaping from a building, possibly a haunted house.

There was a scientist, (possibly mad), probably assisting or being rescued by the children. I think the scientist at one point was wearing jet powered roller skates.

I suspect there were two (mild by today's standards) sinister adults: one male, one female.

In one scene, one of the children must navigate through a "laser field" to disable an alarm system... the "laser field" looked more like glowing orange rods that they had to step between or crawl under / through. This is the most vivid recollection. The movie must have this detail.

I may be confusing the following detail with other movies, but there's the possibility that the boy had a magical harmonica, and the girl could do telepathy with animals.

Thanks in advance for any suggestions,

David

If someone invents a god, and says god punishes murderers, then those who adopt this faith would be less likely to commit murder. Would natural selection therefore favour them?

If, on the other hand, moral relativism prevailed, a larger percentage of the population *may* consider murder to be a valid form of expression, and would not natural selection decrease the population as a result?

Any respectful assistance in understanding the pros and cons of natural selection are welcome.

The best answer will be chosen based on respect, and ability to help me understand natural selection.

If I try to create a new text document by right clicking in windows explorer, a new file is created with a ".V" extension instead of a ".TXT" extension. It still opens with notepad. It used to have a ".VHD" extension until I uninstalled Altera Max / Quartus software - in an attempt to correct the same problem.
