Actually, there are lots of different recipes. Here are some of the best recipes for different types of slime, from normal slimy slime to eerie glow-in-the-dark slime. Some you can eat, some look like snot, toxic waste, or ghoulish dripping blood. Because these recipes don't take a lot of time, (though a few require a trip to the hardware store and not just the kitchen cupboard) you won't want to stop at just one. Throwdown some plastic and get ready for a slime fest! Classic Slime Gary S Chapman / Getty Images This is the classic slime recipe.

It's easy to make and can be used to make interesting shapes. You'll get the best effect with a thin slime and a strong magnet, such as a rare earth magnet or electromagnet. Radioactive-Looking Slime Anne Helmenstine This slime sort of resembles toxic waste, yet it is actually easy to make and safe. The best part is, it requires only a couple of easy-to-find ingredients. Glow-in-the-Dark Slime Anne Helmenstine What is better than regular slime? The slime that glows in the dark, of course! This is an easy and fun project that is suitable for kids.

Put the slime in the refrigerator, and then watch it change color as you play with it. Experiment with cool-drink containers and hot coffee cups. You can add food coloring to expand the colors, too.

You can shape it around objects and sculpt with it. Edible Blood Slime (It Glows!) This edible slime looks like blood and glows blue-white under a black light. Anne Helmenstine Do you need to eat your slime or at least get it near your mouth? Here's a slime that looks like dripping blood, until you shine a black light on it. Then it looks like glowing alien goo. Glitter Slime Shawn Knol/Getty Images You only need three ingredients to make sparkly glitter slime. It's a funny and fanciful variation of one of the classic slime recipes and takes just minutes to make. Flubber Anne Helmenstine Flubber is a non-sticky, rubbery sort of slime. This nontoxic slime is made from fiber and water. Ectoplasm Slime Anne Helmenstine You can make this non-sticky, edible slime from two easy-to-find ingredients. It can be used as ectoplasm for costumes, haunted houses, and Halloween parties. Electroactive Slime Electroactive slime responds to static electricity.

If you use wool or fur to charge up a piece of polystyrene foam and move it toward flowing slime, the slime will stop flowing and will appear to gel. Soap Slime Ralf Stockmann Photography / Getty Imaged This form of slime uses soap as its base. Soap slime is good, clean fun. You can even play with it in the bathtub. Edible Slime Slime can be edible, so it's safe to play with and also eat. Anne Helmenstine Most slime recipes are nontoxic, but there are only a few you can actually eat and none that taste as good as this candy one! Here are additional edible slime recipes, including a chocolate version. Gunk or Goo This non-toxic goo hardens like a solid when you squeeze it but flows like a liquid when you pour it. PamelaJoeMcFarlane / Getty Images This is an interesting nontoxic slime that has properties of both a liquid and a solid. It flows like a liquid, but it hardens when you squeeze it. This slime is easy to make. Fake Snot This slime looks like mucous or snot. Digni / Getty Images Yes, slime snot is gross but not as bad as playing with the real thing, right? Here's a translucent type of slime that you can leave clear or can color greenish-yellow if you prefer. Fun! Silly Putty Silly Putty can flow like a liquid.

Oobleck Slime Oobleck is a slime that changes properties depending on pressure. Dorling Kindersley / Getty Images This nontoxic slime recipe uses starch and glue. The non-sticky goo flows like a liquid yet hardens when you squeeze it. Borax-Free Slime Avoid borax if there is a chance slime could get in your eyes or mouth. RubberBall Productions / Getty Images Borax is used to form the cross-links in many types of slime, but it can irritate skin and isn't something you want young kids to eat. Fortunately, there are several recipes for the slime that don't include borax as an ingredient. Not that you're planning on holding a slime taste-test, but these recipes are safe enough to eat!
