Pseudo Snot
Eeewww! That's gross -- but it's only pseudo snot.

Want to use chemistry to gross out your family and friends? Make some pseudo snot. You might already know that "pseudo" (say "soo-doe") means artificial or pretend, but you may be surprised by how real the pseudo snot will look.

You'll need to wear goggles to make the solution. And while it may seem obvious, do not eat the pseudo snot or drink the borax solution. When you're finished playing your joke, put your pseudo snot in a plastic bag and toss it in the trash -- don't pour it down a sink; it will clog pipes.

What You'll Need:

  • Goggles
  • Borax
  • Measuring cup and spoons
  • 3 small bowls
  • Water
  • Yellow (or green) food coloring
  • White glue
  • Mixing spoon

Step 1: Put on the goggles. Dissolve 1/2 teaspoon borax into 1/4 cup water in the first bowl.

Step 2: Put 3 teaspoons water in second bowl, and add 1 drop yellow

food coloring.

Step 3: Put 1 teaspoon white glue into the third bowl. Stir 1/2 teaspoon yellow water into the glue. Pour 1 teaspoon of the borax solution over the glue, but don't stir it.

Step 4:. Put your fingers into the center of the solution, and pull out a nice long strand of pseudo snot. Find a friend to gross out, and pretend to sneeze -- hold the pseudo snot near your nose. Yuck! You have enough borax solution and yellow water to repeat this five more times. Experiment with different colors to find the perfect snot color.

What Happened?

White glue is made of long strands of proteins. The borax causes these long strands to bond together more tightly, so when you pull the mixture up it looks like a long strand of snot.

What type of solution acts like a liquid and a solid at the same time? Learn all about it on the next page of fun science projects for kids.
