We are SO excited to see Muppets Most Wanted next month in theaters! We absolutely loved the last one and with this movie’s lineup it should be just as good! We thought we’d celebrate today with another fun spy activity.
Write on a piece of paper with milk and a paintbrush or qtip (make sure your paintbrush doesn’t have old paint in it) the thicker the milk the better.
Leave out to dry
To reveal the message a parent can expose the paper to a heat source (hold over a light bulb or candle) this is obviously a bit dangerous so always and only with adults.
I like using an iron (steam turned off)
Send it to someone in the mail with instructions on how to reveal the message for some secretive mail!
