Winner of the 1989 Bafta award for
Best Children's Educational
Programme. More gripping stuff this week: the world's strongest crab - with 50kg of pinch-power; and a trip into the future to find out more about the 'greenhouse effect'. Everything from robots to sealions, and some real owl television when five barn owls fly free in the studio.
With Terry Nutkins , Nicola Davies and Chris Packham Producer Paul Appleby (R)
