Did you know that pumpkin pie filling is a non-Newtonian fluid? Along with custard, other liquids in this category include ketchup, paint, and those slime things the kids all seem to be into these days.
A Newtonian fluid (according to Newton’s Law of Viscosity) can be thought of as a liquid that stays the same thickness no matter how hard you try to mix it. One good example is water. When you move your hand around in a bucket of water, it doesn’t get easier or harder to stir the water. It’s just…water. Booorrrrring. ?
If you mix a bunch of cornstarch into the water, you’ll notice that the mixture gets harder to move (thicker) the more effort you put into trying to stir it. If you stop stirring, the mixture will go back to being thinner. This is how custard behaves. In fact, if you fill a swimming pool full of custard, you can actually walk on it (there are videos on YouTube of this.) If you stop walking, you will start to sink!!
On the other hand, if you pick up a bucket of ketchup or peanut butter (presumably at Costco), you’ll find the opposite happens when you stir it. It might take a little push to get things going, but it gets easier to stir as you keep stirring it (i.e. the fluid gets thinner.) This is why we boop the ketchup bottle to get it to come out.
Did you get any good treats this Halloween, Newtonian or otherwise? What was your favorite?
