Susan J Morris – interviewee in Episode 31 of RpgGamerDad Podcast mentioned
– amongst other pretty amazing info about her D&D game with Erin M Evans –
mentioned making this prop for their game. The players had to use it to mix potions using glowstick fluid, vinegar, baking powder, water and more. Of course, incorrect mixtures resulted in real life explosions. Puts the rest of us lazy GM to shame.
