And what happened then…
Well… in Who-ville they say
That the Grinch’s small heart
Grew three sizes that day!
from How the Grinch Stole Christmas by Dr. Seuss
Can you picture the scene in your head? The Grinch straining as he holds the sleigh balancing precariously on a mountaintop. He hears the singing and then pop, pop, pop, his heart fills with joy.
I love watching How the Grinch Stole Christmas (the cartoon version, not the live-action movie) every year and I was dying to do an activity based on this favorite movie. So, we took a classic science experiment, gave it a Christmas-sy twist. Then voila! We made the Grinch’s heart grow three sizes – or more with this fun Christmas science project.

Before you begin your project, you’ll want to make the Grinch’s small heart. Take a green balloon and use your red Sharpie to draw a simple heart on the balloon. Give it a minute to dry before you begin your project.
Do your science experiment
Carefully, without dumping any baking soda into your bottle, attach the balloon to the top of the water bottle.
You’re all set up! Get ready to grow the Grinch’s heart.
Why did the Grinch’s heart grow?
