8oz/ 235ml Pink - Nontoxic Water-Based Color Dye For Foam Bubble Machines

Add pink color dye to your foam solution mixture to tint the foam as it dumps out of the foam machine. Add more color based upon your desire for color. It's a subjective thing so add as much as you like. You can also color the foam at night with lighting. This saves mess and money. Yes. It stains.
