Hello, welcome along. It is the Fun Kids Science Weekly. My name's Dan. Thank you so much for giving us a listen. It's

actually the final Fun Kids Science Weekly before Christmas. So I'm thinking no matter what you end up

getting for the big day, at least I can give you the present of making your brain loads bigger

with all the smart stuff that we'll talk about

that's happening all around the universe today. This week we'll head to the part of the ocean that is

so deep, no sunlight manages to make it down there. Also we'll catch up with the latest trials of

the Bloodhound car. This is the rocket-powered car that's trying to break the land speed record.

It's for this rather splendid stipendary compendium I'm compiling.

You just ask it how something is made, and it'll oblige with a fulsome explanation. Take this, for example, a plastic bottle,

a common enough item and one with which you'll be well acquainted. But how is a plastic bottle made?

Many plastic bottles are made of a substance called P-E-T.

That's short for polyethylene perephthalate.

It makes bottles that are lightweight and strong, useful when bottles are used for food and drinks.

Step 1

pellets of P-E-T and recitaled plastics are loaded into special ovens and heated to 260 degrees centigrade so that it melts.

This melted plastic is then injected into small moulds.
