If you want to know what's going to be big in tech in 2015, then a huge tech show in Las Vegas might well have the answer!

The Consumer Electronics Show (CES) is the world's biggest annual consumer technology trade show, with more than a whopping 3,500 companies taking part this year.

Starting on Tuesday, top tech companies will show off their latest gadgets.

Here's a peek at some of the futuristic gear that'll be on show:

Drones

One of the highlights is a quadcopter called Zano. It's small enough to fit into your hand, but still powerful enough to film HD quality video.

3D printing

No tech show would be complete without the latest 3D printers. Highlights include the latest in food printing and machines that can build detailed, multicoloured 3D objects like this below, just out of paper and ink.

Smart cars

It's not just small gadgets: there'll be a whole host of self-driving cars including one that allows passengers to face each other (below) and one that you can park just by using a smart-watch app.

Televisions

Look out for new quantum dot TV technology which involves tiny crystals - 50,000 times smaller than a hair - to give better colour quality to what you see on screen. And then there are TVs with nits - not the head lice variety - but more nits means the picture will look much better even in a sunny room.

Weirder stuff

And of course there's more unusual stuff that will be on display.

A toothbrush that plays a video game, a baby's dummy that connects to the net, a ring for your finger to show how many unread emails you have and a dog collar that lets you speak to your pet are all reported to be making an appearance at the huge event.
