Thank you JKP for sharing your story, pretty neat for "top of the head"! I wonder what age you imagined for your audience.
Koen, if you can't wait for "boo-boo" season, you can resort to a strong infusion of green tea, or cook a brew of banana peel (the greener the better). Some rusty bits & strong vinegar, and you're all set.. but that reminds me of another thread I wanted to open
Edit: Fun activity w/ (slightly larger) kids: Invisible ink - write with tea, let dry. Later put a drop of iron vitriol (keep this one out of reach!) on a dabber & rub across writing, which will magically turn pitch black.
