It's pink. It's angry. And it wants you to be angry! It's the river of slime that the Ghostbusters saved NYC from in the 80s. Fortunately, Vigo has been banished--permanently, since there haven't been any instances of of giant Stay Puffed Puft Marshmallow men and the Statue of Liberty has remained firmly anchored in the harbor. But all the same, it might be sort of neat to create your own river of slime to deploy--as long as it was slime that lacked the ability to be emotionally manipulative:
Well, now you can! PopSci has a five minute video on how you can make your own rheopectic slime! What's rheopectic slime? It's slime that doesn't follow Newtonian laws:
Most fluids get less viscous the more you manipulate them--think of how honey or oil become "wetter" as they warm up and more solid as they cool. Those are Newtonian fluids. But non-Newtonian fluids do the opposite: they get more solid the more they're manipulated. So if you let this slime sit on a surface, it will pool out into a flowing mess, but if you play with it, it becomes thicker and bouncier. You can even form it into a ball.
This would have worked perfectly for the river of slime--the slime would have done all the work on it's own in terms of "flowing" forth and conquering the city. To recreate the effect, all you have do is let the slime loose on a flat surface. Maybe strategically place a few miniature figures in the way? So, grab some Borax (use less for flowing slime, more for slime you want to shape), pink food coloring, glue, and water, and get to it! Here's the video: DIY: Make Your Own Slime.
Disclaimer: Kids, don't try this alone. Grab a parent and do it together. Do not eat the slime. (why would you want to? It's slime!)
