Think of a Number

BBC One
on BBC One London

with Johnny Ball and guest singer Angela Presman
A lighthearted exploration of science, technology and numbers. This week Johnny looks into

He cooks, looks, hits, breaks and bends ... glass.
See some glass over 3,000 years old, a teardrop that goes with a bang and a singer who has a smashing time.
Meanwhile, see if you can see through this one. Divide a clock face with two straight lines so that the numbers in each part are equal.
