Watch cricket on telly with lab equipment (4,4)
I believe the answer is:
test tube
'lab equipment' is the definition.
(I've seen this before)
'watch cricket on telly' is the wordplay.
'watch cricket on' becomes 'test' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'telly' becomes 'tube' (I've seen this in another clue).
'test'+'tube'='TEST-TUBE'
'with' is the link.
Can you help me to learn more?
(Other definitions for test tube that I've seen before include "Glass container in the laboratory" , "Glass item in lab" , "used by chemist" , "glass vessel" , "Scientist's cylindrical glass" .)
