Hi class! Today we will do an experiment.

This is great! I'm reading a magazine these days. I saw really cool experiments in it.

That's lovely, Ginny.

Anyway, today's experiment is called elephant's toothpaste.

Now listen to me very carefully.

Take a test tube and put some peroxide in it.

Later at some potassium iodide. You can start the experiment.

Two minutes later.

What are you doing, Ginny?

I'm mixing potassium with water, Miss Brown.

I saw it in the magazine yesterday. I think potassium's colour will change.

What? But that's not the experiment I told you about.

Wait. Potassium with water?

Oh no! Run! It will not change colours. It will explode.

Oh, sorry Miss Brown. I forgot this experiment was in the Don't Try It At Home section.

Go to the principal's office. Now!
