The Hello and welcome to the naked scientists in 2014 I'm Chris Smith and this week

we're taking on your science questions, anything science that you would like to ask.

Already in we'll be finding out how does gravity work in so much as we can answer that.

Also how do hailstones form and if metal sparks in a microwave, why don't microwaves

spark off themselves? Lots more like that coming along. Let's meet this

week's team. Dave Ansel is one of the team. He, last time

was on the program, made ice cream in the kitchen with liquid nitrogen. Very

tasty it was too. Indeed. Yeah, then you told me it came from a pathology department the

liquid nitrogen I did wonder what the lumpy bits were. I can possibly comment.

Also with us is Dominic Ford who is an astronomer and space scientist.

He's always pointing his telescope out of his bedroom window

looking for heavenly bodies.

The next one, but drop the charges, Dominic?

Rock the charges, yes.

Pekyllis, yes. Pekyllis, yes. And alsow, who's a science writer from Cambridge and also in a past life, I think you're a nuclear

or a particle physicist, was it Mark?

I was a chemist.

I did use to work with radioactive material though which was pretty exciting.

If you would like to get a question into them email Chris at the naked scientist

dot com or you can tweet at naked scientist.

Now I've also asked the team to come up with their predictions

for science breakthroughs in 2014.
