You can use the combination to create an invisible ink that turns dark blue when the second chemical is applied. Obviously, it's cheaper to use a lemon and vinegar, but not as much fun. This is a seriously science-laden/engineering heavy table.

Invisible Ink
We used Eryn's Chem C2000 kit this weekend. We added ammonium iron(ii) sulfate, water, and potassium hexacyanoferrate(ii) solution to create a beautiful Prussian blue. The color, not the racist band of little girls who became liberals after a public education. Not that we wouldn't have been pleased as punch to create an anti-racist potion.

I bet Ming would be highly impressed it if Eryn could create Caribbean blue with her chemistry set.
