Shhhhh it’s a secret

30th Jan 2013



Buttons has been booked to host a Spy theme party in March and I’m a tad excited about! I have some fab ideas for games that I will blog about after the party with some pics hopefully.

While I was jotting down ideas it did remind me of a blog I have been meaning to do for ages. I have a children’s book on science projects and  I was looking though it over Christmas and came across this experiment.

Secret letter writing with lemon juice. I think I have known about this at some strange in my life as it rings a bell but I thought I would give it a go for you guys and show you the results.

Making the secret note is pretty simple, squeeze the juice of a lemon in a cup and dip a cotton bub in and use this to wright with.

Making the ‘invisable’ ink turn visible can be a bit harder. I tried mine under and light bulb as the book suggested but no joy. I then called my mum who used to be a science teacher and she said that it should work but the heat source needs to be hot.

I tied again, no joy. Time to call out the big guns! I got the iron out and this was better. It does take awhile and just be careful you don’t over do it and set the paper alight!


Step by Step
