Hi, I'm Jenny with your last Newsround update this Sunday

afternoon. Coming right up: The theatre show to

get kids super-keen on science, and...

Feathers fly as people all over the world join in world Pillow Fight

day! This is Newsround.

First, how much food gets wasted in your home? A new report out today

from a House of Lords committee says far too much food's being thrown

away across Europe each year. It says 90 million tonnes of food is

wasted annually throughout Europe and 15 million tonnes here in the

UK. The report calls for more action to stop the waste and says buy-one,

get-one free offers in supermarkets encourage shoppers to buy more food

than we need. But not everyone agrees that these offers are the

biggest part of the problem. Buy-one, get-one free - there isn't

a lot of evidence that it contributes significantly to food

waste. Clearly, if the retailers have evidence that it does, and

Tesco's did last year on baggage salads, they can stop those

promotions. The main reasons why we are wasting food - there are two

main categories: either we are cooking too much and not using the

leftovers, or we are letting it go off before we use it. That comes

down to us, and the way we plan and shop.

Next, an explosive new theatre performance is aiming to get more

kids interested in science. There's been chaos in Sheffield

today after the city's half marathon was called off because of a lack of

water for runners. Race organisers say they had been let down by a

water supplier, and decided it wasn't safe enough to go ahead.

5,000 runners were due to take part. Despite the cancellation, some of

them still ran the course anyway. We heard it was cancelled, and

before we knew it is everyone just started running and made the race

for ourselves. Sheffield people did fantastic.

Everywhere we went, people were giving out water.

Next, an explosive new theatre performance is aiming to get more

kids interested in science. Banging balloons, fireballs, and freezing

flowers are all part of The Energy Show at the Science Museum in

London. Here's a sneak preview: Do not try this at home!

This demonstration shows the chemical reaction when you ignite a

hydrogen balloon - and the explosive result! It's one of the live

experiments that's part of The Energy Show at the Science Museum in

London. The idea is to have a lot of fun - and to learn a bit of science

at the same time. Most hopefully won't have seen

musical lightning before. I'd never seen it before yesterday! It is

incredible, and it is generally lightning in a cage. I want them to

go and find out about how it all worked.

And there's a virtual Einstein to guide the audience through the

tricky bits! The play is about two science students trying to prove

their knowledge of energy. I learned that you can make

lightning in your kitchen. I never knew that you'd be able to do that.

I thought that only the sky could do it.

I liked it when they tried to blow up the liquid nitrogen.

The show is soon going on tour across England and Wales. And the

hope is that it'll help show that science can be sparky!

Next - can Britain make it into the Semi Finals of the Davis Cup, for

the first time in 33 years? Well that's out of Andy Murray's hands

now. He needed to win his singles match against world number thirteen

Fabio Fogini to send Britain through, but Andy struggled with a

very noisy Italian crowd and his opponent played brilliantly. So

Britain's fate now lies with James Ward, who's up against Andreas Seppi

in the final match. England's women cricketers have lost

to Australia in the final of the World Twenty20 tournament in

Bangladesh. Charlotte Edwards' team set Australia a target of 106 to win

and couldn't prevent the Aussies from reaching that target with ease,

with plenty of time and wickets to spare. The result is a repeat of

2012's final. Next - get ready for our regular

round-up of the weirdest news stories of the week. Take it away

Nel! First up: robot police. A team of

engineers in America have developed the Nightscope K5. It's about 1.5

metres tall, and has special built in cameras to detect when things go

wrong. When you get on a plane, there is

usually a bit of time before take-off. What you do to pass the

time? If you were to cast off The Lion King musical, you belt out a

rendition of the Circle of Life. The Australian cast did on a plane in

Brisbane as they were waiting for take-off. Now that's what I call

in-flight entertainment! Have you ever imagined what it would

be like to have special powers? Well, one young boy's dreams came

true when his dad used some pretty nifty special effects to turn him

into a superhero. It's all down to his dad Daniel's skills with a

computer - but then James's dad does work for world-famous animation

company DreamWorks, which made films like Shrek and Kung Fu Panda. I

wonder if he'd turned me into Wonder Woman?

Last up - feathers have been flying all over the planet to celebrate

World Pillow Fight Day! Hundreds of people took part in this pillow

fight in Hong Kong - with some teenagers using it as an excuse to

let off steam before exam time! The annual event has been going since

2008. That's all from me, Newsround's back

bright and early tomorrow morning. But if you can't wait until then,

there's loads of stuff on the
