A new holiday science programme with a difference.... you can take part!
Paddy Feeny will be phoning children all over the country and putting them on the line to the panel of resident scientists. You can talk to Patrick Moore about space travel and astronomy, and to Professor Richard Gregory about inventions and how the brain works.
This week's guest is Professor Eric Ash. who would be interested to answer questions about the way everything and anything in the world works.
You can hear ARTHUR GARRATT telling you how to use yourself as a guinea-pig for some amusing experiments.
