Hacker serves up some killer questions to Andy Murray.

But first to the debate over the latest playground must-haves!. Loom

bands have been sweeping through schools over recent months but some

schools have banned them because they say they're too distracting.

They're the latest in a long line of trends so Ricky's been looking into

how long the fascination with them could last.

Over the years, we've had hulahoops, conkers, and my favourite,

the electronic, portable pet, Tamagotchi.

Playground trends are nothing new in the latest one involves these

tiny rubber bands, which can be made into these bracelets,

They are taking over schools all over the world,

I like loom bands because they make me join

They reflect on how you are feeling and you can make a black or

And if you're happy, you can make a white and yellow one.

I like the individuality and how you can express yourself

Loom bands are made with hundreds of brightly coloured rubber bands,

woven together using a special board, called a loom.

The kits with all the coloured bands and

the loom itself cost around ?5, and each individual band costs around

Not everyone thinks they are a good idea.

Some schools have actually banned them.

Yeah, I can see why some schools have banned them, but we control it.

The kids now they're not allowed them during lesson times.

As soon as it disrupted their learning and

teaching, it wouldn't necessarily be banned, but the children would be

talked to about them and they would be told to leave them at home.

In a world where we spend so much time using technology,

If anyone had a special card, they would see there is something special

about themselves. With any trend, there is a potential for causing

things like bullying, but if we talk about any positive way, we can see

whether it is a piece of card or a rubber band, it is just a bit of

fun. In a world where we spend

so much time using technology, there is a lot of praise for these

loom band for bringing craft back But as with most trends,

how long until these loom bands I bet someone somewhere is

thinking of the new big thing. And you've been telling us what you

think of loom bands Class 5B in Bristol say they're a

great way to keep kids occupied instead of spending loads of time on

computers. Next, to a sports day with a big

difference and with the Commonwealth Games just around the corner

of different sports and Martin went More than 700 schoolkids from across

Birmingham have been invited here to this special Commonwealth Games

field event. And it is all for National School Sport Week. They'll

get to try out a range of different sports and also have their very own

opening ceremony. Each kid here today, is under a flag

of a Commonwealth country, so they When they watch it, they can support

the countries they represented a. What kind of things have you been

doing? 50 metres sprint, shot put, long jump... I am here with Team

Scotland! We have got to do new sports we haven't done before. It

teaches us important things. We like Scotland. It is important to involve

children in sport. You don't know what you can do unless you try. I

was rubbish at that went on but I kept doing it and did not give up.

Sport is fun, and as you can see everyone here is having a good time.

All eyes will be on Glasgow for the Commonwealth Games in one month. It

is nice to see these guys getting into the 70s early. I have already

found my team. Scotland! Typical. Thanks, Martin.

In other news, the decision on which of the world's biggest problems to

try and solve has been announced. The Longitude Prize asked the public

night on the One Show it was announced ?10 million will be put

into finding out how to develop new antiobiotic medicines.

Wimbledon news now - British women's number one Heather Watson faces her

toughest test later today. She's playing her second round match

semi-finalist. Meanwhile, Andy Murray made easy work of Blaz Rola

in his second round match yesterday. But he had a much harder challenge

afterwards - the dog owner faced up to CBBC's Hacker T Dog...

I've heard some lovely stuff about you...

I'm a border terrier, what do you think about that?

You look very different to my two, to be honest.

They chase a lot of squirrels and stuff...

Do you know what I call squirrels? What?
