Oobleck !!!

Oobleck is a classic science experiment that's great for kids. You should see it in action and I am sure you too will have your hands covered with it along with your kids!!!
Oobleck is one of the non-newtonian fluids. It acts like a liquid when it is poured and like a solid when a force is applied on it. You can grab it but then it will ooze out of your hands. 
It gets the name from the Dr. Seuss book, Bartholomew and the Oobleck where a gooey green substance, Oobleck, fell from the sky and wreaked havoc in the kingdom. 
  
After reading the book last week, we HAD to make Oobleck again. To make it mix 2 cups of Corn starch to one cup of water and thats it !! 
Slowly mix the corn starch and the water with your hands.  Putti loves the feel of it...
Food coloring is optional. But we love adding it. Putti chose blue this time. It is a little challenge to get the color mixed in thoroughly. You will have to slowly mix the Oobleck around. Ohh look at the lovely marbling effect as the color mixes...
Grab a handful, squeeze it, and let it ooze out your fingers....
 Try and see if you can shape it into a ball ..

 Spoon it...
  Pour the Oobleck into another container.....
 

  • Because the cornflour particles are suspended in water, it is able to flow like a liquid.
  • When you apply force to it by squeezing or hitting it, the particles lock together and act as a solid.
  • Make a puddle and quickly drag your fingers through it.
  • Punch the oobleck and see what happens.
  • Jab at the Oobleck and then slowly let your finger sink in.
  • You could store the Oobleck in a plastic container/bag to use later. We put ours in refrigerator.
  • Do NOT put any Oobleck in the drains!
  • Have Fun !!!!
