Painting with Invisible Ink

We had plenty of ideas for British Science Week at the end of March.

Painting with invisible ink is fun and so easy to do!

Mix fresh lemon juice and water in a bowl, and use a paintbrush to paint a secret picture on a fresh sheet of white paper.

(Older children can use a cotton bud and write a secret note!)

Leave the paper to dry then slowly heat the paper under a light bulb. The heat will turn the lemon juice brown, and your magic picture will appear!

We’d love to know if you try this and how you get on!
