Oobleck is a non-Newtonian fluid, you can make some at home

Experiments aficionado TheBackyardScientist is back to show what happens when his absolute favorite metal, molten aluminum, meets regular, everyday substances.

This time, he pours molten aluminum into a pint of oobleck, a non-Newtonian fluid that displays properties of both solids and liquids in that it lets you dip your hand in it just like a liquid but feels solid when punched or squeezed.

Apparently, he did this experiment to please fans who explicitly asked to see what would happen when somebody poured molten aluminum into oobleck.

“Many of you suggested for me to pour molten aluminum into Oobleck. It sounded like a fun experiment so I gave it a go!” TheBackyardScientist explains in the video's description.

He begins by cooking some oobleck simply by mixing some corn starch with water. He also adds some food coloring, not because he needs to but for the effect.

When he gets around to pouring the molten metal into the oobleck, nothing spectacular happens. True, there are some bubbles and smoke, but no explosion or anything of the kind occurs. Kind of a bummer, but at least nobody was injured.

Then, when he gets the oobleck spiced with molten aluminum out of the experiment pint, he finds the heat turned the non-Newtonian fluid into a jelly of sorts.

As for the metal, the dipping in the oobleck merely solidified it into blotch-shaped sculptures. The science enthusiast seems a wee disappointed, but as it turns out, home experiments aren't always all fun and blasts.
