15 Valentines Science Activities You Are Sure To Love

Valentines science

We are going to share our favorite Valentine's science activity with you first and then, we'll let a few of our internet-science-blogger friends share the rest!

1. Send a Valentine's note with Science.

Now, we will warn you - Uncle Cecil has activated the smoke alarms more than a few times with the typical version of this activity. You know the one with lemon juice or milk and a candle.

It's all too easy to see your secret note go up in flames, so we are going to share a different spin on this one. One that we learned from the Kitchen Pantry Scientist. This one uses acid and base action instead.

Here's what you will need:

  • Baking soda
  • Water
  • Q-tip
  • Small bowl
  • Paper
  • Cranberry juice
  • 9 by 12 pan

Mix a tablespoon and warm water in the small bowl. Dip the q-tip into the solution and use it to write a message on the paper. Let the paper dry.

Once your message dries, hand the paper to your friend. Have your friend fill the 9 by 12 pan with cranberry juice. Then, have your friend set the paper you gave them in the pan and wait for the message to be revealed!

And once you send a Valentine's note with science, check out these fourteen more Valentine's science activities you are sure to love!
