Oobleck: Messy science or hard core chemistry?

Today, the Seniors explored the science behind combining a solid with a liquid.
We used these ingredients and formula...Oobleck
And proceeded to make, what is know in the biz, as a non-Newtonian fluid.

Here are our reflections and photos:

I learnt that when you clench your hands with the Oobleck it’s hard, then when you open your hands it melts – Jackson
Oobleck is a strange substance. It can be a liquid, a solid or it can be gooey. It really depends on how much cornstarch and water you have. It needs a balance - Tia
Oobleck can be pretty liquidy, like if you add too much water but then it can be a solid, which is when you add too much corn flour. It is complex to work with. It was messy to mix and create, but very fun to squish or play with. It really depends on how you do it, but I think it was fun and really taught us how it is going by the concept of science (if you mix something it might change, react and make something completely different to what you started with). Overall it was really cool and fun – Madi
Oobleck was good because it was like a liquid, but when you touched it was a solid – Tully
Oobleck is really weird because when you put pressure on it, it turns hard and when its not being squeezed it’s a liquid
Oobleck is very strange because, when you squeeze is, it’s a solid but when you let go it turns Into liquid – Ava
It’s very messy and when you pick it up and play around with it’s a solid and when you leave it in your hand it’s a liquid – Natasha and Jessica and Natalie
It’s great fun to get your hands deep in. If you don’t use much water it looks like a liquid but it’s actual a solid – Natalia B and Isabella
I was really messy and if you put pressure on it, it turned into a solid – Tom and Oliver
It was really fun, but kinda weird to touch because when the two ingredients went together they felt weird – Will
I thought that the oobleck was different than normal things when you put them together. It made them feel uncomfortable – Jenny
I thought it was weird because it looked watery, but it was actually a solid – Ava M
It was confusing because it looks like a liquid and it drips like a liquid, but it’s hard – Piers
It was strange how it looks like a liquid, but it’s actually a solid and when you put pressure on it, it goes all liquidy and after a while it goes floury – Cooper M
As I first touched it, it  felt gooey and as time went on it started to get hard and putting more water on it made it squishy – Zac
The oobleck was very messy. It looked wet, but it was actually really hard – Pat and Cooper T.
The oobleck was messy. When you picked it up it was hard, but then it dripped down your hands – Lochie

  1. Looks like lots of messy fun. Now I know what the white stuff is on Cooper's school shirt!

  2. Oobleck sounds like a load of fun. Where does the name originate from? Are there any similarities between oobleck and slime (the green, gooey stuff you can buy)?
