Two hundred and seventy gallons of oobleck later, and Anthony Carboni and Tara Long are ready to roll.
Carboni and Long are the hosts of Hard Science, an educational YouTube show where, according to Carboni, "we use just a little bit of knowledge about the world and use it to bend it to our whim." A new episode shows them creating oobleck, a non-Newtonian fluid with some very interesting properties.
Non-Newtonian fluids don't behave entirely like liquids or solids, but like something in between. They respond differently depending on the amount of force applied to them, as demonstrated to comic effect in the video above.
If oobleck physics is complicated, the recipe for the stuff is surprisingly simple. Just mix two parts cornstarch for every one part water.
