Before Lush introduced us to the bath bomb, we collected bath pearls: little rubbery beads full of scented oil that came in all manner of colours, sizes, and shapes. Everyone had that one friend who had a whole jar or dish full by the bath, a carefully curated collection of starfish, dolphins, hearts, and turtles, none of which ever actually ended up in the bath. Though these babies have all but disappeared off the shelves, Amazon stocks a Dolphin Bath Pearl Pack (£11) if you fancy reminiscing.
