Oobleck (under construction, working on the picture issue)

I've been trying to get these pictures rotated correctly and the things that usually work aren't this time. So bear with me, I have a fun video clip too but it's also sideways and my brain can't take it today. :)




Yep, it's as messy and as fun as the name sounds. Ooblek is a non-newtonian liquid. That is, it acts like a liquid when being poured but like a solid when a force is acting on it. You can grab it and then it will ooze out of your hands. Make enough and you can even walk on it (Mythbusters did this on one episode). Scientists haven't decided yet what makes oobleck behave like this. Of course none of this will make sense to your kids. But for the science geeks out there.....(my husband is one so of course we had to look up the properties).

Oobleck is a classic science experiment that's perfect for entertaining little kids and big kids (that includes adults). If you haven't seen it in action it's fascinating stuff and before long you'll have your hands covered with it, happily making a mess that can be washed away with water.


Oobleck gets it's name form the Dr. Seuss book Bartholomew and the Oobleck where a gooey green substance, Oobleck, fell from the sky and wreaked havoc in the kingdom.

I pre-measured all the ingredients and then let my daughter pour them together and mix them up. We decided to play with mixing colors at the same time so she picked two colors and we played till we got a new color. My daughter is at an age where body functions are funny so when our blue and yellow turned green.....yep, boogers! Think ahead on this one :)


2 parts corn starch
1 part water
food coloring of your choice (will stain, may want to use newspapers and an apron)


(we ended up adding a little more water as we went along because it got too hard to play with)
