Help! Quicksand!!!

We did some great work today exploring states of matter . We looked at Oobleck, a mixture of starch and water that's actually kind of tough to classify. It looks and feels like a liquid until you push or pull on it with great force.

Then we learned about quicksand, another mixture that behaves in the same strange way. Although these days, quicksand is not high on our list of worries, neither was a pandemic 2 months ago... Should someone fall into some quicksand, we wanted to know what's the best way to get them out: yanking them quickly or with slow movements.
