Have you read my post on Kinetic Sand yet? Well, I wrote in that post that I will be putting together a tip for all of you about OOBLECK and how to make it, so that your kids can have tons of fun playing with it. So here it is, enjoy…
Oobleck has a similar (but definitely not the same), texture as kinetic sand. Oobleck or Goopy Goop (as it is also known), is another sensory play wonder that my kids love to experiment and get creative with.
To read more about the benefits of sensory play, read my post on Kinetic Sand.
Oobleck is a fascinating science experiment for kids of all ages (adults too). It was originally the name given to a type of sticky slimey liquid in a 1949 Dr. Seuss children’s book (Bartholomew and the Oobleck). This liquid fell from the sky as a result of the king becoming bored with normal weather and it was capable of gumming up a whole kingdom.
The Oobleck that we make is really incredible and can behave like a solid or a liquid depending on how much pressure you apply to it. If you try to grab some in your hand it will form a solid ball in your palm until you release the pressure. Then, it will flow out slowly between your fingers. Totally amazing!
This is how you make this fun gloop:
- They can drive toy cars through it (the cars and any other plastic toys wash off very easily), pour it through a strainer or a dish with holes in it, send it down a marble run or half pipe, add dish-washing liquid to it for a soapy experience… Use your imagination and go wild!
This is one that we have not tried yet but it sounds fantastic:
If you have a lot of cornstarch and a small pool or shell, you can supersize this experiment and actually walk or run on the surface without sinking! But, once you stop moving, you will begin slowly sinking into the liquid.
A few ideas that I will be trying soon:
- to freeze Oobleck,
- paint with it on sidewalks and
- to make it dance on a speaker covered with plastic.
When you are finished having fun with your Oobleck, just pour or scrape it into a plastic container, put a lid on it and place it in your fridge to store it for another wonderful time of creativity. Mine lasted about two months before it started going mouldy.
Have I left any ideas out? Let me know in the comments area below. Thanks!
