[00:00:00]Ride on the magic school bus.

[00:00:04]HERE IT, LIZ.

[00:00:08]WOOHOO!

[00:00:09]HEY, WHAT HAPPENED? WHAT'S GOING ON?

[00:00:11]Where are we going?

[00:00:15]>> [music] [cheering] >> I know that smell. It's gasoline. I hate that smell. Get used to it, Arnold.

[00:00:25]We're inside the bus's gas tank. Okay, so the question is, how does the gas get from all the way back here to all the way up in the engine? That way.

[00:00:34]The gas is going into some kind of tunnel or pipe. As Christopher Columbus said when he set sail to look for America, All aboard FOR PARTS UNKNOWN.

[00:00:51]OUR MEN, THE OARS, me hearties. Full speed ahead.

[00:00:57]Stroke.

[00:00:58]Stroke.

[00:01:04]Faster. Faster.

[00:01:07]The sooner that bus is out of my life, the better.

[00:01:22]Friz to Liz. Friz to Liz. Come in, please.

[00:01:31]We're moving out of the fuel tank and into the fuel line. Stand by.

[00:01:36]Ready? Set. Go!

[00:01:38]It's a tight squeeze in here. I guess gas doesn't need a lot of room to get to the engine. Look up ahead. The gas seems to be trying to get through, but it's blocked by something.

[00:01:52]Is it just me, or is that peanut butter I smell?

[00:01:56]It is peanut butter. Maybe this is what's stopping the gas from getting through to the engine.

[00:02:02]>> And without gas, the engine won't run.

[00:02:05]That's it! [screaming] Make way for the gas!

[00:02:10]But what's peanut butter doing inside the fuel line? Yeah.

[00:02:15]Good question.

[00:02:18]JUNK IT!

[00:02:20]WE'RE ALMOST THERE. Step on it. I'm getting an award today. [music] Did I tell you? Twice.

[00:02:27]Oh.

[00:02:29]Line's clear, Ms. Frizzle. The gas is flowing again. Then the engine should start. Right, Ms. Frizzle? Oh, we'll soon find out. Seats, everyone.

[00:02:41]Turn the key, Liz!

[00:02:48]>> [music] >> Where are we?

[00:03:12]Are we inside the engine, Ms. Frizzle?

[00:03:14]Technically, no. We've just been pumped into the carburetor.

[00:03:19]Oh, my favorite place. Keep pumping, Liz!

[00:03:26]I don't get it. We got the gas flowing.

[00:03:29]How come the engine won't start? Maybe it needs more than just gas. Uh, maybe it's too chilly in here for the gas to work. Yeah, I feel a draft, too. It's coming from that opening up there. Right you are, Tim. Air! Of course. Don't you remember what we learned in fire safety?

[00:03:50]You need air for things to burn. And since a running engine burns gas, the engine needs gas and air to run. Well, we're not getting that much air. That's because something's covering the opening. Hmm. A peanut butter sandwich.

[00:04:08]Junk it!
