The Challenge

When you drop Mystery Science Goo, it splats. Suppose you wanted a goo that bounced when you dropped it.

That's our challenge for you. We want you to make a goo that bounces.

Start with the Mystery Science Goo recipe. Think about the properties of this goo make it splat. What do you need to change to make it bounce?

Discuss with your friends. Then check out our ideas.

Bouncy Goo — Our Ideas

We decided Mystery Science Goo needed to be firmer to bounce. So we experimented with adding powdery stuff to the recipe to make firmer goo.

Here are our three new recipes:

  • 1 Tbsp talcum powder, 2 Tbsp of glue/water solution, & 1 Tbsp of borax solution
  • 1 Tbsp cornstarch, 2 Tbsp of glue/water solution, & 1 Tbsp of borax solution
  • 1 tsp salt, 2 Tbsp of glue/water solution, & 1 Tbsp of borax solution

Try all three and compare the resulting goos. Which one bounces highest?

For more information on goo recipes, visit the Page that Dripped Slime on the Bizarre Stuff website.

Activity Prep

Print Prep

This lesson develops the idea that chemical reactions create new materials that have useful and interesting properties. The Great Goo Experiment is a two-part activity. In Part 1, students experiment by combining different substances and watching for reactions. In Part 2, students mix glue and borax solution in clear plastic bags to observe the reaction, which creates "Mystery Goo."

Preview activity
COVID-19 Adaptations
Digital worksheets available
Teacher demo recommended

Students at home
Set up Part 1 of the activity as a demonstration and go through Steps 1 - 11 over video conference. Students need the Goo Testing worksheet (printed or digital) to record their observations. We suggest you skip Part 2 of the activity if students are at home, especially if students are working without adult helpers.
Students at school
Do Part 1 of the activity (Steps 1 - 11) as a demonstration. Each student needs a Goo Testing worksheet to record their observations. Students can do Part 2 of the activity solo. In Step 14, each student will need to hold the bag open and pour the substances in on their own.
