Make an Oobleck or Fake Snow at Home!

A few weeks ago, my daughter’s STEM teacher had the kids make ‘snow’ at home with some easy kitchen ingredients.  We experimented more and ended up making our own Oobleck!  

❓What is an Oobleck❓

An Oobleck is a substance that can mimic the properties of a solid and a liquid simultaneously.  These are also known as ‘non-Newtonian’ fluids.  Other examples of non-Newtonian fluids are ketchup, silly putty, or kinetic sand!

❗How to make it: ❗

To make the fake snow ❄️, add equal parts baking soda and cornstarch. Then add water 💦 a little bit at a time and mix it with your fingers 🖐️ until it forms together to make snowballs ☃️.

If you want to turn it into a cool Oobleck, just keep adding some water 💦 to it until you get the right consistency.  (You can skip the baking soda all together and just use cornstarch and water.)

❗ Do not throw your Oobleck down the sink.  It can clog the pipes. You can either throw it away or leave it to dry out then throw it away. ❗

⭐Interesting fact⭐

The word Oobleck actually came from a Dr. Suess book 📚, “Bartholomew and the Oobleck”.  In the story a mysterious gooey green substance falls from the sky called an Oobleck.
