making oobleck to celebrate Dr. Seuss’s Birthday today.
This stuff is amazing. My boys (okay and me too) were totally taken with this goo. Oobleck defies Newton’s third law of motion–for every action, there is an equal and opposite reaction. If you quickly smack oobleck with your hand it immediately turns into a solid, instead of splashing or moving. If you slowly move oobleck it reacts like a liquid. Needless to say our oobleck took a lot of fist smacking! Our kitchen was filled with lots of “Wow,” “Cool,” wide eyes of amazement and much laughter!”
To make your own mix 2 cups of cornstarch and 1 cup water in a bowl. If you want to color your oobleck like we did, add a few drops of food coloring to the water before adding to the cornstarch. It took some effort to mix the water and cornstarch. Try it out (hit it with your fist and pour it off a spoon to see if it works) before you give into the urge to add more water to make it easier to mix. When the kids weren’t playing with it I covered it with plastic wrap.
Too Cool! Really, you must give it a try!

We love that stuff at our house. The first time I made it, I added too much fod coloring, and our hands were blue for quite a while.

no way!! I have an ancient childhood memory of seeing this on some kid’s science show. I was just telling my husband about it about 2 weeks ago – how there was this amzing liquid that was solid when you hit it!! I never knew what the stuff was made of (and never thought to look it up).

Just being a nerd – the adjective to describe the way the cornstarch mix is behaving is “thixotropic”
Love the website by the way. I’m a knitter (in the UK), getting back into sewing, and have been looking at some fab ideas on blogs! I’ve bookmarked yours!!!!

Excellent! This is neat-o. Thank you so much for putting this up. I am going to measure out 1/2 portions, with directions, and give them to my daughter’s pre-school class for St. Patrick’s Day. A cool alternative to candy!

I love making this with kids! We add dinosaurs and other toys that don’t have moving parts and pretend that they are in a swamp or quick sand. You can put it in plastic shoe box or something with a little more room.

Thanks for the recipe. 3 drops of red food coloring is plenty to make the substance pink (my daughter’s FAVORITE color).
I had a blast with it!!!

My daughter is having her first sleepover for her birthday. She will be turning 9 years old)My daughter is having 10 girls over(not including her and her sister) The theme is Hello Kitty. The times will be from fri. 6pm – 10am sat.
Am I crazy to have agreed to this . I have no ideas and I am usually very creative. I am an artist and I was an art teacher. I love kids but I do not know how to fill the time or make it fun.
My daughter is like Martha Stewart Jr. she thinks she has all the plans . I need some good sleepover/Hello Kitty ideas. Do you have any?
