This video is about Invisible Inks and Secret Writing - concealing messages on Eggs and Newspaper. Dr. Macrakis author of "Prisoners, Lovers, and Spies - the Story of Invisible Inks" pays a visit to Jason Lye's kitchen where the two of them use household materials to hide secret messages. Dr. Macrakis' book comes out April 2014, and contains an appendix by Dr. Macrakis and Jason describing sympathetic ink experiments that can be performed using materials available at the store.
