Highlighters

Besides Highlighters, What ways are there to make liquid in bottles glow with a blacklight?

Right now I have a lot of memory bottles filled with some water and the highlighter sponges. But It seems like the only colors that really work are orange and green. Do you have any other ideas?

1. Mountain Dew will glow if mixed with peroxide and baking soda!! Watch this video on how to make your own glow bottles: http://www.metacafe.com/watch/855279/mountain_dew_glows_mountain_dew_light_hack/ After i saw this I won't drink Mt. Dew anymore....
2. Use glowsticks. You can get them in all different kinds of sizes and work great.
3. The Mountain Dew with peroxide and baking soda is a fake video. They use a glow stick, but they leave that info out. The only other option to highlighters is Tonic Water. Tonic Water contains quinine which also glows under a black light. But highlighters glow better. However, you can safely consume tonic water... so it's cool to use for glowing jello, or whatever.
