Germs are basically a malevolent form of bacteria, with one purpose: to spread germs.
S1Germs
You can pick up germs from a variety of sources, and because they're invisible they're almost impossible to see.
Moth apples are smaller than crab apples, sweeter too. Don't be tempted to eat them, as they are highly explosive.
S1Ghosts
But there's no need to be scared of ghosts, it's a very childish attitude as the majority of them are quite harmless. This spirit is helping a girl with her homework, while this one is mending its master's caravan.
Ghosts. You may know them as ghouls or demons or spirits or spirims or spictrims.
One way in which ghosts are different from man is that they can't whistle. Try as they might, the most they can muster is a rather feeble hiss. Perhaps it's because their lips are transparent and their tongues are see-through?
S1Sulphur
We will be using a household object famous for its iron content. Can you guess what it is? Correct. Champagne.
(Talking about heat vision) You've probably seen this in action at your local dump, where it is used by the waste disposal industry.
In an average year we get through roughly forty tonnes of sulphur. This translates into approximately two and a half million individual matches. Since the company was formed we've produced 156,280,000 matches, and if we continue at the current rate of production, by the year 3500 we will have manufactured 900,000 billion billion billion billion billion billion matches.
Narrator: That's a lot of matches!
S1Iron
We are going to be feeding both an AC and a DC current through the ferric pyramid, and so the battery itself is connected directly to the mains. We're working with AC/DC because it's heavy metal.
An enormous pair of scissors has appeared in the sky directly above the laboratory, and after a few moments, it's gone. It's an old experiment that you've probably seen before, but well worth trying nonetheless.
Here is a model of an iron molecule. And here is a model of a model, modeled in iron.
Man has been using iron since the stone age.
S1The Brain
What is the brain? If you don't know that, you've forgotten how to think.
The brain is basically a wrinkled bag of skin, filled with warm water, veins and thought muscles. Think of it as a kind of modified heart, only with a mind or brain.
