Hello, welcome along to the show. My name's Dan and there's no time for fuss, no time for

waffle and chat. We've got lots to do. We've got a whole universe to explore. Come on. This is

the Fun Kids Science Weekly podcast and this week we'll talk about a stinging nettle so dangerous

and I'll answer some of the questions that you've left as a review over on the Apple podcast store.

Today, they're on eyes and on vultures being sick. That's on the way first. Let's catch up

with one of our favourite geniuses here on the Science Weekly,

letting us know how everything around us is actually made. It's Sir Sidney McSprocket.

How's it made?

Oh, hello, Sir Sydney McSprocket here. I've been in action capturing facts all about manufacturing. It's for this

rather splendid stipendary compendium and compiling. You just ask it how something is made,

and it'll oblige with a fulsome explanation. I'm getting stuck in to some sticky tape.

So stick around, you might learn something.

Ha ha ha!

These will make the clear plastic part of the tape.

Step two.

The melted plastic is spread over wide conveyor belts and dried to form a very thin, clear plastic sheet, which is wound onto giant rolls.

Step three.

An adhesive, that's the gluey, sticky bit, is prepared.

Different types of tape use different adhesives.
