This is how to make awesome slime on a budget. All you need is arrowroot flour (available for about 5 to 8 bucks at Walmart, and optional color. (tempura kids paint for around a buck at a dollar store)

The video shows 3 cups of water to 1/4 cup arrowroot flour, but you could go 3 quarts to 1/4 quart or multiply the amounts any way you like. Adding color to the water is optional, but results in more fun. The slime is very very slimy, and also stringy and stretchy too, just a perfect combination of all the best features of slimes. Caution # 1: Be sure slime is cool enough to play with. A fast way to cool it is to put the pan you heated it in in a sink and add cold water, stirring the slime in the pot so the outer edges and bottom of the pot transfer the coolness of the water. Not stirring could cause a skin to form over the slime. Caution # 2: Be sure you keep stirring while heating this up, as the bottom of the pot will be hottest and you could have thick slime forming there while the rest of it is still liquid. Keep stirring and this won't happen. The slime thickens almost instantly once the liquid reaches about 180F, so there is no need to boil it or keep heating. It won't make it any thicker. As it cools, the thickness and sliminess will increase. So for about ten bucks, a person could make gallons of this stuff and it's got a great consistency. One last benefit to this: It's quite easy to rinse off. Other slimes take a lot of water to dissolve, or a scrubby in the shower to remove it from the skin. Some are liquid plastics. This, on the other hand, comes right off with water and is 100% natural.
