The Secret Side of the Neill-Cochran House Museum
What about invisible ink?
Methods of producing invisible messages have existed since antiquity, and though the principles of making and developing inks are well known, even as late as 2011, the US Government was hesitant to declassify documents written about (and with!) invisible inks.
This Sunday, we will experiment with the 3 common principles of making and reading messages written in invisible ink – developing with heat, developing with acid-base reactions, and visualizing using ultraviolet light – all with safe, non-toxic materials. How do you disguise and deliver an invisible ink message? Which kind of ink works best? We’ll let you be the judge.
Oh! Sunday Funday with invisible ink!
Museum staff and volunteers will be on hand to supply message making materials and help with developing messages using gentle heat, fruit juice, and ultraviolet light. Especially shrewd spy-investigators can also try their hands at deciphering hidden messages in sample prepared documents and in completing our spy-themed museum scavenger hunt.
Weather permitting, we will also set up snacks and lawn games on the museum’s front lawn.
Join us this Sunday from 1 to 4pm. No RSVP required, but if you want to invite a friend, sign up and share on our facebook page.
Whether this is your first Sunday with us or whether you’re coming back for more, this Sunday is especially important because we’re participating in Amplify Austin for the very first time! Sunday Funday will always be free, but if you like what we do, schedule your donation on our Amplify Austin page, come back and visit us on Tuesday, March 8th for our Stitching Memory’s reception, and spread the word about what we add (do to amplify?) our community. Our goal is to raise $2,500 to make Sunday Fundays bigger, better, and, well, funner next year. Help us show Austin how much our little old house means to the community!
