Why do we moan so much

Most were American. Not to say all Americans are like that, but the lack of knowledge of how the rest of the world lives is staggering. And the exchanges kept descending into slanging matches - nothing to do with the subject.

People can be so stupid as that just shows.

They are ingenious. Great use of a waste product too.

Saw a picture,somewhere online, of a raft made of old plastic water bottles.

I found some of the comments below the video incredibly ignorant, for instance asking why they don't just open a window, they should get electricity or buy clear plastic roofing, does it work at night, and so on.

The sun is so strong there, that the bottles do give a lot of light, just like any skylight. Without a small amount of bleach the water in the bottles would soon turn green, and stop the light. It was amazing to see how much difference is made.

That was brilliant, I didn't understand how it worked.

It's just so simple.

MiceElf They don't give light, the light shines through them as if througha window. I think the water is to strengthen the plastic bottle which would get squashed other wise and the bleach is to prevent the growth of algae in the sunlight.

I agree about the bleach leaking crimson. The sunlight might perish the plastic and make it weaker.

I've heard of this being done, here's the youtube, it has to do with the solution absorbing sunlight www.youtube.com/watch?v=kHTD_RX3J2I. Brilliant. As for the leaking and the bleach damaging eyes, as my DH would say that's risk averse plus!

I'm worried that, if it leaks the bleach could damage their eyes .

I didn't see it. I'm sure I'm being thick, but how does bleach and water give light?

Came across these via a Canadian friend a while ago. Brilliant idea.

That's why we are called whinging, whining poms.

Isn't it part of being British?

Saw this programme as well - wonderful - so simple, so clever- brilliant.

(And yes, too much moaning around generally).
