0:46:50 > 0:46:57.
0:47:00 > 0:47:02It's a brand-new term
0:47:02 > 0:47:06and CBBC have sent these four magicians back to school.
0:47:06 > 0:47:10They're pretending to be supply teachers so that they can perform
0:47:10 > 0:47:14amazing magic on unsuspecting classes.
0:47:14 > 0:47:16But because you know and love them,
0:47:16 > 0:47:19this time we've cunningly disguised them.
0:47:29 > 0:47:30This time it's Fergus.
0:47:30 > 0:47:34The disguise is on, the hidden cameras are set.
0:47:34 > 0:47:36He made it for his Year Six class.
0:47:36 > 0:47:40Today, we're going to be talking about cloning.
0:47:40 > 0:47:44Cloning is making an exact replica of an object or item.
0:47:44 > 0:47:46Everything in this room,
0:47:46 > 0:47:50everything around us has a molecular map like a code, right?
0:47:50 > 0:47:52If you can work out that code,
0:47:52 > 0:47:55then in theory you can replicate another object from nothing.
0:47:55 > 0:47:58For cloning to occur, you need two fundamental things.
0:48:00 > 0:48:05The first one is this is rather cool generator. How cool is that?
0:48:05 > 0:48:11Now this generator actually strips and defuses the DNA.
0:48:11 > 0:48:13The next stage is...
0:48:13 > 0:48:17to send that DNA along a wire.
0:48:17 > 0:48:20To a receiver which is here.
0:48:20 > 0:48:22This is my cloning cloth.
0:48:22 > 0:48:23What the receiver does,
0:48:23 > 0:48:26it takes the information which is processed by the generator,
0:48:26 > 0:48:30then it rebuilds it into a real object, an actual physical object.
0:48:30 > 0:48:35- So you will see on the table I've got an...?- Egg.- Good.
0:48:35 > 0:48:39If I place the egg onto the generator,
0:48:39 > 0:48:41turn the generator on.
0:48:42 > 0:48:46Now I program it to read the DNA of the egg.
0:48:46 > 0:48:50The machine is part of the magic. It cannot clone DNA.
0:48:50 > 0:48:52In fact DNA could stand for,
0:48:52 > 0:48:54Does Nothing Actually.
0:48:54 > 0:48:56Now if I take my cloning cloth...
0:48:56 > 0:48:58Check it out, the cloth is empty.
0:48:58 > 0:48:59..and I attach this wire.
0:48:59 > 0:49:03All I need to do now is press the transfuser.
0:49:03 > 0:49:09It sends the DNA it's processed all the way along to the cloning cloth.
0:49:09 > 0:49:12If we wait just the right amount of time...
0:49:15 > 0:49:22..incredibly, we end up with an identical egg.
0:49:22 > 0:49:25- CHILDREN:- Whoa!
0:49:25 > 0:49:26How great is that?
0:49:28 > 0:49:31Now, if you leave it for just a moment to set,
0:49:31 > 0:49:35you can actually reach right in and you will see
0:49:35 > 0:49:39it looks like a real egg, cracks like real egg, look at that.
0:49:39 > 0:49:41But obviously, once is OK,
0:49:41 > 0:49:45but what if I could do it again?
0:49:45 > 0:49:48All I need to do is attach the wire again.
0:49:48 > 0:49:51Press the transfuser - it sends that information
0:49:51 > 0:49:53along to the cloning cloth.
0:49:53 > 0:49:59When I take the wire off, we get another egg. Isn't that crazy?
0:50:02 > 0:50:06Now, we are going to try and do this with another small item - a toy car.
0:50:06 > 0:50:11So we are going to change that with the egg. The egg can go away.
0:50:11 > 0:50:13I put the egg away.
0:50:13 > 0:50:16I place the toy car onto the generator.
0:50:16 > 0:50:21We program the machine to read the molecular structure of the car.
0:50:21 > 0:50:24Then we attach the wire to the cloning cloth, just like before.
0:50:24 > 0:50:27Press the... Can anyone remember the name of the button?
0:50:27 > 0:50:30- Transfuser.- Excellent.
0:50:30 > 0:50:33That information travels along to the cloning cloth
0:50:33 > 0:50:35and we now have a...
0:50:35 > 0:50:37toy car.
0:50:37 > 0:50:39Oh!
0:50:39 > 0:50:43- How incredible is that?- But here comes the most amazing magic.
0:50:43 > 0:50:48Do you remember I said this wasn't a sophisticated piece of machinery?
0:50:48 > 0:50:51So do you know what the strangest part is?
0:50:51 > 0:50:55- Everything's gone.- Ohhh!
0:50:55 > 0:50:57Who enjoyed that experiment?
0:50:57 > 0:50:59Me!
0:50:59 > 0:51:01This lesson has been unforgettable.
0:51:01 > 0:51:04But there is one last trick.
0:51:04 > 0:51:06And... Oh! I forgot to mention one more thing!
0:51:06 > 0:51:08I didn't have the original machine.
0:51:08 > 0:51:10I actually had a clone of the cloning machine.
0:51:10 > 0:51:14Do you remember what happened with all the items in the box?
0:51:14 > 0:51:17It is exactly the same with the machine. Watch.
0:51:17 > 0:51:20- That vanishes as well.- Oh!
0:51:20 > 0:51:21Incredible!
0:51:21 > 0:51:23And now it is time to fess up.
0:51:23 > 0:51:25Now...
0:51:25 > 0:51:27I have a slight confession.
0:51:27 > 0:51:30My name isn't even Mr Robinson.
0:51:30 > 0:51:33And all of you have been set up by your teachers, by your headmaster,
0:51:33 > 0:51:36by your family, by your friends.
0:51:36 > 0:51:40You're all being filmed right now for CBBC.
0:51:40 > 0:51:42There is a hidden camera there! SHOUTING
0:51:42 > 0:51:46There is a hidden camera there for Help! My Supply Teacher's Magic!
0:51:46 > 0:51:50An amazing trick, and this class didn't realise.
