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.

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."
