This week, Kirsty and Jonelle become women in STEM to investigate which is dirtier: your water bottle or a pub toilet?
And we quiz BBC Radio 1’s Melvin Odoom on how often he REALLY cleans his bottle…
Plus, Love Islander and campaigner Sharon Gaffka talks about her miscarriage – and why a new certificate to recognise baby loss will help those going through it.
