Imagine you want to do something with DNA, perhaps you'd like to sequence something, or stick some in on orange, or beer yeast.
So you have this bit of DNA, but it's so incredibly tiny and fragile, it's almost not real, it's more like the idea of a thing then a thing.
So you use one of these PCR machines to make your idea real. You put your tiny, fragile sequence in and out comes a robust bucket full of DNA!
