Oobleck is an ooey gooey slime substance that’s also a terrific classic science project. Learn about non-Newtonian fluids while digging your hands into a neat tactile sensory experience too. Once you learn how to make oobleck, you can give it fun themes like this Snowflake Oobleck. Explore Non-newtonian fluids easily at home or in the classroom with common kitchen supplies.

SNOWFLAKE OOBLECK

Snowflake oobleck is a great winter science and science sensory play activity all in one that will keep the kids busy for quite a while! Winter is an excellent time of the year to put a little twist on classic science experiments!

WHAT IS OOBLECK?

Oobleck is a classic science experiment made from two easy ingredients. Check out Dr. Seuss’s book, Bartholomew And The Oobleck, to go along with your activity. 

Homemade oobleck is a mixture of cornstarch and water. Roughly a 2:1 ratio, but you can tinker with the ratio to find the desired consistency that still maintains the properties of oobleck. Learn how to make oobleck in just a few simple steps

What’s the science of oobleck? Well, it’s solid. No, wait, it’s a liquid! Wait again; it’s both!

It’s very fascinating to be exact. Pick up solid chunks,  pack it into a ball and watch it ooze into a liquid. This is called a non-newtonian liquid, a substance that acts like both a liquid and a solid. Read more about it here.

HOW TO MAKE SNOWFLAKE OOBLECK!

Snowflake-themed activities are perfect for young kids to explore the winter season! To learn more about snowflakes, check out these YouTube videos about snowflake science. Or, if you want to learn how to draw snowflakes, check out this tutorial.

SUPPLIES:

  • Cornstarch
  • Water
  • Glitter
  • Kid Tweezers (optional)
  • Snowflake ornaments and buttons
  • Cookie sheet (we use the dollar store variety for projects!)

INSTRUCTIONS:

  • Mix up one cup of cornstarch and 1/2 cup of water! Pour in some glitter if desired! You can adjust the ratios as needed, but this recipe is a general guideline!
  • Pour and spoon onto a cookie sheet and stick in your snowflakes!
  • Add a pair of tweezers if you like. Tweezers make great science tools and also encourage fine motor skills.

THE SCIENCE OF OOBLECK

Oobleck is a fun substance made from a mixture of cornstarch and water. It’s a bit messy too!

Oobleck is called a non-Newtonian fluid. This means it is neither a liquid nor a solid! You can pick up a clump of the substance like a solid and then watch it ooze back into the bowl like a liquid.

Touch the surface lightly, and it will feel firm and solid. If you apply more pressure,  your fingers will sink into it like a liquid.
