I would like to add some color to the liquid on this faded 90's lamp. It performs beautifully but would benefit from some color.
Question 1: How do I remove the cap and can it be put back on afterwards?
Question 2: Can I add a food coloring to the liquid?
Please ignore the scotch tape on the cap. I tried to twist it off but that didn't work. Fearing I might have destroyed the seal, I put the tape on, (none of which has impacted the performance of the lamp.)
As usual, many thanks for your help and advice!
