Bath water colouring?

[GreenDinosaur]

I remember having some stuff that made your bath water different colours when I was a kid, is that still a thing?
Not bubble bath but just colour.
If so, can anyone recommend some that don't stain the bath or the child please?

Our bath water comes out yellow anyway!

Second DandyScandi and colour my bath. We used some last night for ‘potions’.

Really vivid and no staining. No good for milk allergy’s though as they have lactose in them.

Lush do a unicorn batch bomb that looks amazing.

Yep, colour my bath. Lasts for ages

Colour my bath has just arrived from Amazon, thanks vipers! Also got some bath bombs with dinosaurs in for stocking fillers, quite excited for Christmas now!
