How to Make Slime
To make basic slime, first mix 3/4 cups of water (180 milliliters) with 1/2 a cup (125 milliliters) of glue. Add a few drops of food coloring if you want colored slime. Then, in a separate bowl, mix 1 cup of water (240 milliliters) with 1 teaspoon of borax until it's fully dissolved. This mixture is the slime activator. Slowly add 1 teaspoon of the slime activator at a time, stirring after each addition, until the slime starts to thicken. Finally, knead the slime until the ingredients are fully combined. If your slime still feels a bit too slimy, add a little more of the slime activator until it feels right.
Mix the borax powder and warm water together. Measure out 4 tablespoons (59 ml) borax powder and 1 cup (240 ml) warm water. Add these ingredients to a large mixing bowl. Stir the mixture until the borax is completely dissolved. A substitute for borax and water mixture is contact lense solution (the measurements vary). Add 2 cups (470 ml) of water and 1 cup of glue to a separate mixing bowl.  Add food coloring to the glue mixture (optional). Choose any color food coloring you like! feel free to experiment with any color. Start with a few drops of food coloring, then stir. If you want the color to be brighter, add a few more drops of the food coloring. If you add a lot, the color may end up pretty dark and when you play with it, the color will dye your hands. You can also separate the glue mixture evenly into smaller bowls and make each one a different color, then mix them together. Combine the two mixtures. Dump the borax mixture slowly and a small bit at a time, because if you add too much, your slime will be hard and rip not stretch! If you use contact lense solution pour it in slowly and mix. Keep mixing until the slime/mixture starts to pull away from the side of the bowl. Stir them together until it becomes your desired consistency, and doesn't stick to your hand. You will see the slime begin to form! If you chose to make smaller amounts of slime in separate containers, evenly divide the borax solution among the containers. Start kneading the slime with your hands at this point. It might be sticky, but keep mixing. Add more activator (borax) if needed. Take the slime out and have fun! If it is too sticky, add more of the borax and water mixture until it gets to a texture that you like. Mix 3⁄4 cup (180 ml) cornstarch with 2 cups (470 ml) vegetable oil. Add both ingredients to a large bowl. Stir them together thoroughly. Put the mixture in the refrigerator. Place the bowl in the refrigerator and leave it there until the mixture is fully chilled (about one hour). The cold temperature will help the slime solidify and reach the ideal consistency. Remove the mixture from the refrigerator. Stir it well (as the ingredients will have separated again). Let the mixture warm up just enough so that it flows slightly. Find a block of styrofoam. It can really be any size but the standard size is 1x6x6 inches (25x150x150mm). Run the styrofoam on your hair or on your carpet several times to give it a static charge. Pour the slime mixture out slowly into another container. Place the piece of styrofoam just in front of the slime before you start pouring. It should be about 1 inch (25 mm) away from the flow of slime. The static electricity will cause the slime to stop flowing and appear to take on a life of its own. Wiggle the styrofoam around and the slime should follow it. Your kids will be amazed! Pour a can of sweetened condensed milk into a pan. Place the pan on your stove top. Add 1 tablespoon (15 ml) of cornstarch to the milk and stir until the ingredients are well-combined. Heat the mixture over low heat. Set your burner to low and continue to stir the mixture constantly as it heats up. If you don't stir continuously, the mixture may stick to your pan. Remove the mixture from the heat when it has thickened. As it heats up, the slime will become more gelatinous and harder to stir. Once it reaches that point, remove the pan from the heat. Add 10 to 15 drops of food coloring to the mixture. You can choose any color that you want! Green is always a classic, but experiment or allow your kids to pick a color. Allow the mixture to cool. Before you let your kids play with (and eat) it, let it cool down completely. The slime may stain surfaces, so make sure it's kept away from anything that stains easily or that you want to keep unstained, especially light colored objects. Mix 1 cup (240 ml) soap flakes with 4 cups (950 ml) hot water. Carefully add the hot water to a large bowl. Measure out the soap flakes and place them into the container. Stir thoroughly until the flakes fully dissolve. Add a few drops of food coloring (if desired). Food coloring is optional, but it may make the slime more fun! Let the mixture stand for up to an hour. This will allow the mixture to reach the desired consistency. Beat the mixture vigorously with a spoon. It will begin to froth up as you beat it. It has reached the right consistency when it pours easily and becomes extremely slimy to touch. Keep the slime in an airtight container. This slime keeps very well in an airtight container. Make sure you store it away from direct sunlight and heat.
