Cute! 70 00:03:52,362 --> 00:03:56,783 It seems we don't have enough evidence to know that the basement's haunted. 71 00:03:56,866 --> 00:04:00,912 -Aww, phooey! So there's no ghost. -I'm not saying that. 72 00:04:00,995 --> 00:04:04,624 Sometimes, things that seem spooky have logical explanations. 73 00:04:04,707 --> 00:04:09,462 -I know what we should do. -Something super safe and not scary? 74 00:04:10,129 --> 00:04:13,633 No, find out if there's a ghost in the basement! 75 00:04:13,716 --> 00:04:15,468 I was afraid you'd say that. 76 00:04:15,551 --> 00:04:19,264 I think it's time to haunt our brains with ideas. 77 00:04:19,347 --> 00:04:20,932 We need a brainstorm. 78 00:04:21,015 --> 00:04:23,851 What if we invite a ghost over? 79 00:04:23,935 --> 00:04:28,106 The new ghost can go to the basement, tell us if there's another ghost. 80 00:04:28,189 --> 00:04:30,608 But then there would be two ghosts. 81 00:04:31,818 --> 00:04:32,902 Iggy's right. 82 00:04:32,986 --> 00:04:37,031 Two ghosts could be a problem 'cause they might not get along. 83 00:04:37,115 --> 00:04:40,410 You don't want ghost drama in your house. Trust me. 84 00:04:40,493 --> 00:04:44,664 What we need is a way to see ghosts even when they're invisible. 85 00:04:45,331 --> 00:04:48,960 We should make ghost goggles.

Stick to stuff. 285 00:15:43,864 --> 00:15:47,743 Cold-blooded animals can't regulate the heat inside their bodies. 286 00:15:47,826 --> 00:15:49,620 What if we make Lil' Liz 287 00:15:49,703 --> 00:15:52,998 a warm bowl of cricket noodle soup with berries? 288 00:15:53,082 --> 00:15:56,877 Lil' Liz only eats live insects, and she doesn't like warm fruit. 289 00:15:56,961 --> 00:16:01,715 I've got it! We could use dragon breath to heat a hot tub for her! 290 00:16:01,799 --> 00:16:05,636 Dragons have a lot of free time in autumn. It's their off-season. 291 00:16:05,719 --> 00:16:07,763 Dragon breath is probably too hot! 292 00:16:07,846 --> 00:16:08,973 Definitely. 293 00:16:09,056 --> 00:16:10,432 Yeah, true. 294 00:16:10,516 --> 00:16:12,935 What if there was a way to use hot water 295 00:16:13,018 --> 00:16:16,438 to warm Liz up without getting her too hot? Be right back! 296 00:16:16,522 --> 00:16:20,401 Boom! Hot water bottle. You pour warm water inside. It heats up. 297 00:16:20,484 --> 00:16:23,445 Those only stay warm for, like, 20 minutes, right? 298 00:16:23,529 --> 00:16:28,242 And we need to keep Lil' Liz warm until the pet shop opens tomorrow. 299 00:16:28,325 --> 00:16:29,868 Aww, snap! You're right! 300 00:16:29,952 --> 00:16:32,329 If dad's fibreglass wasn't off-limits, 301 00:16:32,413 --> 00:16:34,999 we could wrap Liz in that to keep her warm. 302 00:16:35,082 --> 00:16:36,834 You're onto something. 303 00:16:36,917 --> 00:16:39,837 Dad's using the fibreglass to insulate the garage. 304 00:16:39,920 --> 00:16:43,215 So maybe we could insulate Lil' Liz's terrarium. 305 00:16:43,298 --> 00:16:47,094 -Let's ask him what else we could use. -Insulation is so cool. 306 00:16:47,177 --> 00:16:50,723 Here's what you need to know. Heat flows from warm to cold. 307 00:16:50,806 --> 00:16:54,101 Insulation slows the flow. That's how places stay warm. 308 00:16:54,184 --> 00:16:59,523 Things used as insulators, it just has to trap air and hold together in humidity. 309 00:16:59,606 --> 00:17:01,108 That's water in the air. 310 00:17:01,191 --> 00:17:05,112 That's right. Insulation's cool, right? Or should I say warm? 311 00:17:06,030 --> 00:17:09,575 I love insulation and dad jokes. 312 00:17:10,409 --> 00:17:12,953 She meant to say "cool" dad jokes. 313 00:17:13,037 --> 00:17:16,707 Let's run tests to find the right insulation for the terrarium. 314 00:17:16,790 --> 00:17:19,126 Insulation simulations? 315 00:17:19,209 --> 00:17:22,755 Fab-tastic idea! What about candy floss? 316 00:17:22,838 --> 00:17:25,924 It looks like fibreglass, but we can touch it. 317 00:17:26,008 --> 00:17:29,094 -Plus, delicious! -Great idea. Let's test it. 318 00:17:29,178 --> 00:17:32,389 While you test, I'm going to get Lil Liz's lounge. 319 00:17:32,473 --> 00:17:33,807 Be right back, girl. 320 00:17:35,726 --> 00:17:38,604 We need to find out if candy floss will trap air 321 00:17:38,687 --> 00:17:40,939 and hold together in humid conditions. 322 00:17:41,023 --> 00:17:44,902 So, let's test it with something warm and wet. 323 00:17:44,985 --> 00:17:49,490 -We could fill a beaker with warm water. -Then wrap it with a test insulator. 324 00:17:49,573 --> 00:17:52,618 I'll test the temperature at the beginning and end 325 00:17:52,701 --> 00:17:55,996 to see if the water stays warm. Let's get our materials. 326 00:18:03,420 --> 00:18:05,255 Candy floss is yum! 327 00:18:05,339 --> 00:18:06,799 I mean, done. 328 00:18:12,054 --> 00:18:14,973 Starting temperature, warm. 329 00:18:15,057 --> 00:18:20,354 No air's escaping, so the candy floss must be trapping it. 330 00:18:20,437 --> 00:18:23,690 -Oh, no! -But it doesn't hold up in humidity. 331 00:18:23,774 --> 00:18:25,984 -So that's a fail. -Aww, man. 332 00:18:26,068 --> 00:18:28,487 But this fail is still a win. 333 00:18:30,781 --> 00:18:35,035 What if we use aluminium foil? My mum uses it to keep food warm. 334 00:18:35,119 --> 00:18:35,994 Great idea. 335 00:18:37,955 --> 00:18:40,499 Starting temperature, warm. 336 00:18:40,582 --> 00:18:44,086 -No air's escaping. -Humidity didn't ruin the foil. 337 00:18:45,420 --> 00:18:48,632 -And the water's still warm. -We're ready to insulate. 338 00:18:48,715 --> 00:18:50,592 First, the hot water bottle. 339 00:18:51,260 --> 00:18:53,637 Oh, my gosh, I think it's working! 340 00:18:53,720 --> 00:18:54,805 I'll add the foil. 341 00:18:56,682 --> 00:18:58,851 Lil' Liz is squinting. A lot. 342 00:18:58,934 --> 00:19:02,688 Maybe the light reflecting off the foil is too bright for her. 343 00:19:02,771 --> 00:19:04,356 Aww, phooey! 344 00:19:04,439 --> 00:19:09,153 So far, our insulation simulations are a flop! 345 00:19:09,236 --> 00:19:13,073 -I'm going to set up Lil' Liz's lounge. -Okay. 346 00:19:13,657 --> 00:19:16,827 Why is it so hard to find an insulation material 347 00:19:16,910 --> 00:19:19,621 to keep Lil' Liz's terrarium warm? 348 00:19:19,705 --> 00:19:24,293 Whoopsies! Sorry, Ada. I think I just wrinkled your denim jacket. 349 00:19:24,376 --> 00:19:28,005 Wait! My denim jacket. It keeps me warm when it's cold 350 00:19:28,088 --> 00:19:30,674 and doesn't fall apart when humid outside. 351 00:19:30,757 --> 00:19:35,137 So you want to make Lil' Liz a denim jacket… 352 00:19:35,220 --> 00:19:37,973 I'll get right on it! What are you thinking? 353 00:19:38,056 --> 00:19:41,977 Glitter sleeves? Furry collar? Rhinestone buttons? 354 00:19:42,644 --> 00:19:45,772 We should test denim as an insulation material. 355 00:19:45,856 --> 00:19:49,484 But we can't cut up my jacket. I guess it was a good idea. 356 00:19:49,568 --> 00:19:51,361 Here. You can cut mine. 357 00:19:51,445 --> 00:19:54,781 If you can use it to help Lil' Liz, the rip was worth it. 358 00:19:54,865 --> 00:19:58,368 But I can't watch you rip it any more. So I'll wait outside. 359 00:19:58,452 --> 00:20:00,412 -Thanks, Arthur! -Yes! 360 00:20:05,876 --> 00:20:08,420 Starting temperature, warm. 361 00:20:08,503 --> 00:20:11,840 -The denim's trapping the air! -It's holding up! 362 00:20:11,924 --> 00:20:14,593 Ending temperature, still warm. 363 00:20:14,676 --> 00:20:18,055 -I love denim! -Let's see if it works in the terrarium. 364 00:20:26,396 --> 00:20:29,066 Denim's a great insulation material. 365 00:20:29,149 --> 00:20:32,361 -Yee-haw! -I heard cheering.
