Bartholomew and the GLOWING Oobleck

The oddest thing happened last night.  I wrote this post months ago, and last night it disappeared into cyber space.  It is one of my favorite activities, so I decided it was worth re posting.  This was the first time the boys and I made Oobleck, and we have since made it almost weekly.  It is an amazing sensory experience comparable to no other, in my opinion.

Making Oobleck is simple:

1 part cornstarch

1 part water

 

We don't measure.  We add water to the cornstarch until it is the consistency we like.

 

On this particular night, the first time we made Oobleck, we made it after reading Dr. Seuss' Bartholomew and the Oobleck.  We spent two weeks doing activities inspired by our favorite books by Dr. Seuss, and Oobleck was definitely a highlight.  A good friend of mine is an elementary teacher, and she is the one who gave me the idea.  When I originally wrote the post, I had no idea that Oobleck is also known by another name, Goop.  Many of my favorite bloggers have experimented with Goop in different ways!  Since falling in love with Oobleck I've enjoyed reading about new ways to add to our play.

When we did this, we happened to be on a glowing kick, so for an added sensory experience I used Glow Water to make our Oobleck.

Once adding the Glow Water to the cornstarch, the mixture gave off a nice glow.

Note:  We used about half of the pitcher.

Oobleck is seriously the coolest thing ever.

It is both a solid and a liquid.  One second you can grab a solid handful, then it drips through your hands like a liquid.

JZ was mesmerized.  He scooped handfuls and watched the Oobleck drip through his fingers again and again.

JM asked to put his feet in the Oobleck.  I moved the bin to the bath tub, so the boys could go nuts without spraying Oobleck all over. 

A black light is necessary for the Glow Water to really glow.  While the glowing Oobleck was neat, Oobleck is cool on its own.  If you don't have a black light , don't let that stop you from trying Oobleck!  Even my husband who shies away from our messy fun couldn't keep his hands out of it.
