These are wonderful!! I love how all the different colors work together and pop so well (and that eyeball stopper is so great!). What did you fill them with to get them to pop so well..I have tried the various things I have seen online...tonic water, highlighters etc. Perhaps its the brightness of the uv bulb I use but they don't pop like yours. (Perhaps you address it in the video but the video keeps giving me an error when I try to play). Thanks for sharing!
