Children’s show from 80s or 90s with telepathic children and an alien appearing as a ball of light [duplicate]

Question

Unfortunately I have very limited memories of this show, but it’s most likely either from the late '80s or early '90s. It’s a live action show, not animated.

I remember a group of kids interacting with an alien, which I remember as a ball of light. The children had a telepathic connection between themselves, and also with the alien. There was also some evil organization (as always) that wanted to capture the alien.

I remember one episode where the children are building different platonic shapes for some purpose. When they build a pyramid and one is partially inside it they’re like “hey why aren’t you answering to me?” and they realize the pyramid shape is blocking their telepathy.

I think the pyramid was supposed to be used to capture the alien by some evil people.

Answer 1

I suspect this was the 1984 BBC adaptation of John Wyndham's book Chocky (1968).

The first series followed a single boy, Matthew, who was communicating with the alien intelligence which was represented on-screen as a ball of light - see this clip for example.

The subsequent two series, Chocky's Children and Chocky's Challenge, which I don't think were based on the book, involved more children - and apparently a military organisation that wanted to capture Chocky.

Answer 2

This sounds like "Out of This World" (1987-1991). If the kids could stop time by touching the tips of their index fingers together, then this is the show.

From IMDb:

The series revolves around Evie Ethel Garland, who is the daughter of Troy and Donna Garland. However, Troy is an alien from the planet Antereus. As a benefit of her half-alien parentage, Evie develops three powers as the series progresses. She can pause and un-pause time, "gleep" objects into existence, and can transport herself from one place to another. Troy is living on Antereus and is never seen, but Evie talks to him via a crystal cube. Evie is thirteen at the beginning of the series and lives with her mother in Marlowe, California. Visitors to the Garland home include Donna's brother Beano Froelich; the mayor Kyle Applegate, a former actor; Lindsey Selkirk, Evie's best friend; Chris Fuller, Evie's boyfriend; and Buzz, who tends to take things literally. Episodes usually revolve around Evie getting herself out of a situation that she has caused.
