0:00:03 > 0:00:05That's it. Very good.
0:00:05 > 0:00:09Bobby and Lenny are feeling crafty.
0:00:09 > 0:00:12They're making a volcano with plastic bottles and paper.
0:00:12 > 0:00:15What we need to do next, boys, is quite messy.
0:00:15 > 0:00:16Dad's helping.
0:00:16 > 0:00:20- You all right with that one, yeah? - I like messy.
0:00:20 > 0:00:25Tear bits up, about this size. Here, Len. Curl it up into a ball.
0:00:25 > 0:00:28Bobby, put yours, mix it in the mixture.
0:00:28 > 0:00:31- Dad, is that big enough? - That's it, great. Mix it in.
0:00:31 > 0:00:34Squish the paper and glue together.
0:00:34 > 0:00:36Now put your bit round here.
0:00:36 > 0:00:39- Right, down there. Fill all the spaces.- Is that right?
0:00:39 > 0:00:43- Yeah, that's great. - I'll put this here.
0:00:43 > 0:00:47- What sort of noises does a volcano make?- Like this!
0:00:47 > 0:00:49Pshhhh!
0:00:49 > 0:00:51Great volcano noise, Bobby!
0:00:53 > 0:00:57Strips of paper make a smooth papier-mache surface.
0:00:58 > 0:01:01Well done then. Put your hands in the glue.
0:01:01 > 0:01:04Rub them together and then smooth it over.
0:01:04 > 0:01:07That's very good. Smooth it over the whole lot, Len.
0:01:07 > 0:01:10- So there's lava under the ground and...- That's it.
0:01:10 > 0:01:12..and it goes over here and...
0:01:12 > 0:01:15And it comes out the top. That's right.
0:01:15 > 0:01:18Bobby knows a lot about volcanoes.
0:01:18 > 0:01:21The boys will have to leave the volcano to dry for a while.
0:01:21 > 0:01:24And now it has. They can paint it.
0:01:26 > 0:01:29Do you think we should do one side blue and one side green?
0:01:29 > 0:01:31Start about here.
0:01:31 > 0:01:34All the way around here up to that sea, yeah?
0:01:34 > 0:01:38This volcano has the sea on one side and grass on the other.
0:01:38 > 0:01:42What sort of animals live in the grass?
0:01:42 > 0:01:45- Worms.- Worms?- Yeah.
0:01:45 > 0:01:48- What about tigers?- Yeah.
0:01:48 > 0:01:51- And lions.- Elephant?- Yeah.
0:01:51 > 0:01:55- And grasshoppers.- Maybe.
0:01:55 > 0:02:00- Yeah.- Monkeys.- Monkeys. You're a little monkey.
0:02:00 > 0:02:04A few finishing touches.
0:02:04 > 0:02:05Finished.
0:02:05 > 0:02:09Dad's adding some kitchen ingredients to make pretend lava,
0:02:09 > 0:02:11including food colouring.
0:02:11 > 0:02:15Seven, six, five, four, three, two, one!
0:02:17 > 0:02:19Look at that! Look at the lava, look!
0:02:22 > 0:02:26Look, look at that big bubble on the top!
0:02:26 > 0:02:29Oh, pop it, pop the bubble!
0:02:29 > 0:02:30I think we've nearly run out.
0:02:30 > 0:02:33How about some orange food colouring?
0:02:41 > 0:02:43- And now it looks like real fire. - Does it?
0:02:43 > 0:02:46- Looks really good, doesn't it? - Really cool.
0:02:46 > 0:02:49- I think it's amazing.- Wow!
