Sometimes there are people who figure out how to make something through 4th grade science, package it, and say it’s a product. While it is thankfully pretty easy to spot, there are going to be some who fall pry to its wiles. Hopefully you lot aren’t those people.
The Non-Newtonian Putty 4-Pack does seem weird and awesome. However, this is clearly just cornstarch and water. There is a recipe here, and the video below shows how awesome its properties are. If you want to purchase this rather than make it yourself, it will cost you $12 (and shipping most likely).
