Is your water bottle DIRTIER than a toilet? Reliable Sauce investigates

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.
