🧪 Science with Sarah: Invisible ink 🕵️

👉 Watch the video of Sarah’s school science experiment here!

Hello parents, teachers and students! Here’s a fun experiment that Sherlock Holmes would be proud of, exploring the science of chemical reactions!

Be sure to check out GMSA@9 on Wednesdays when Meteorologist Sarah Spivey does the demonstrations and explains the science behind it.

Science with Sarah: Invite KSAT to your school for live science experiments. (KSAT)


Materials for invisible ink experiment (Copyright KSAT 2023 – All rights reserved)
  • Baking soda
  • Grape juice concentrate (like the stuff in the freezer isle!)
  • Index card
  • Paint brush


  • In a cup, mix some water and baking soda. There should be enough baking soda in the water solution so that it looks cloudy
  • Using a Q-tip dipped into the baking soda and water solution, draw or write something onto the index card. Allow it to dry
  • Paint the grape juice concentrate onto the index card and watch as your drawing magically comes into view. It should look like this ⬇️

Chemical Reaction

Baking soda is a base while the grape juice is an acid. Whenever an acid and a base combine, some sort of chemical reaction occurs. In this case, the baking soda and water solution turns a darker color, becoming visible!


If you’d like Sarah and David to come to your school and conduct a science experiment live on KSAT, email sciencewithsarah@ksat.com.

Parents and guardians: upload a video of your child performing the activity by clicking here. Send it in and you might see it on GMSA @ 9 a.m.!
