Episode of possible anthology series where fairies were cage

There was this CITV ( en.wikipedia.org/wiki/CITV ) programme, possibly anthology series, from the mid-late 90's which had one episode, that was blatantly inspired by the Cottingley Fairies case (https://en.wikipedia.org/wiki/Cottingley_Fairies). The episode in questioned featured some Edwardian children that were capturing fairies and putting them in either jars or cages. In the end, the fairies manage to escape, with one of them smiling, revealing that they have sharp teeth and implying that they may not be that friendly at all.



Can anyone tell me what this show or episode was called or even if it exists??
