Here's another weird thing I thought of doing while I'm churning out a HUGE PROJECT (it's a surprise hopefully coming soon!): what if I painted with a glowstick? I cracked and cut that thing open and painted the contents on a simple cardboard basil, which was surprising how effective the glow could be visible to my phone and how easy to work with the liquid transferring from the brush to the cardboard! I'm Definitely gonna attempt this with a more intricate drawing considering the results!

*BE CAREFUL!*
(As FAR as I know of, the glow liquid is only a mild irritant: it's pretty much hydrogen peroxide mixing with an oxalate ester and a dye to capture the energy release (the broken glass is more of a hazard).
