Science · 30 min · Any age · You and your child together

Discover how a simple liquid can transform into a solid food right in your kitchen. This Spark challenges you to turn cream into butter, exploring the amazing physical changes that happen when you shake it! Get ready to prepare a delicious homemade treat for your Thanksgiving table.

What your child gets out of it

• Observe and describe a physical transformation from liquid cream to solid butter.
• Understand that shaking introduces energy that separates fat from liquid in cream.
• Identify the different components created during the churning process (butter, buttermilk).

What you need

• Heavy cream — A full cup (240ml) or more works best. Make sure it's fresh and cold from the fridge. (or Whipping cream)
• Jar with lid — A clear glass jar (like a jam jar) lets you see the transformation happening. Make sure the lid seals tightly! (or Clean plastic container with secure lid)
• Spoon
• Bowl
• Salt — Optional, for flavor.
• Cold water — Essential for rinsing the butter properly. (or Ice water)
• Crackers — For tasting your fresh butter. (or Bread, Toast)
