How Does It Work

If you’ve been around Steve Spangler Science, you know how much we love slime, but usually we use polyvinyl alcohol and a borax solution. We maintain that it’s the best formula for slime, but you can’t eat it. Fiber powder (like Metamucil) contains an active ingredient called psyllium hydrophilic mucilloid. When fiber powder and water are heated, they will form a consistency that is ooey-gooey and… well… slimy! The best part, though, is that it’s completely edible!
