Have you heard of Flubber? If not, why not? Flubber is awesome. It's really similar to slime but it's watery and breakable. That's not a bad thing though, it's still just as cool!
Slime is much more stretchy and mouldable, but we love how clear flubber is. You can even bounce it like a ball. People often make flubber green coloured, just like the original character Flubber from the old movie. You can even do hilarious pranks with it, watch while some brave fools put it to the test and drop an iPhone 100 ft with just flubber for protection!
