Imagine a world without toys. Scary thought, right? The truth is, without chemistry and other science, some of our favorite toys like slime, action figures, and bouncing balls would not exist. Why? These toys are made of chemicals that make them work! As we wrap up this week, you'll get to experiment with a few more chemical reactions in order to create your very own slime, learn about wild substances like Oobleck (no, we did not make that up), and more.

What were some of your favorite things you learned about chemistry this week?
If you could magically turn into slime, what would you look like? What color and other things would you be mixed with, and when would it be handy to turn into it?

Why Is Ketchup So Hard to Pour?
If you think about it, ketchup acts really, really weird. Sometimes it won't come out of the bottle at all. Other times, it gushes out all over your fries. Why?
Get to Know Oobleck
Get to know who? Oobleck is a type of substance that sometimes acts like a liquid and sometimes acts like a solid. Think quicksand or silly putty. It also has the best name ever. Let's take a closer look with Crash Course Kids.
Slime doesn't just exist in the toy store or laboratory. It also lives in the wild, in the form of slime molds. Want to watch one on the move?
Ready to Make Some Fluffy Slime?
Of course you are! See what happens when you mix a little shaving cream, water, food coloring and glue. This can get messy, so do it so someplace where it's easy to clean up, like a kitchen counter. (Younger kinda campers will also need some help from a grown-up.)
Mad Scientist Questions
After making your slime, think about these questions:
1. Did a physical change or chemical change take place to make your slime?
2. Is slime a solid or liquid?
3. Does your slime float or sink in water? Why?
Whew! We’ve been working out a lot this week (see any chemical changes to those muscles yet?). Let's visit our favorite gym teacher, Joe, and end the week with a good sweat. Try it at least twice!
