# How do you beat the fourth room of the Portal: The Flash Version map pack?

I seem to be having trouble in the fourth room of the Portal The Flash Version Map Pack. It's kind of irritating because, well, it's just the fourth room! This one should be child's play!

The second part of the fourth room in the map pack seems as if it's meant to be analogous to room 6 in the flash game, but the same trick doesn't quite appear to work here. Any hints/tips?

• I don't really know which room you're talking about, they aren't numbered. – a cat Oct 23 '11 at 17:08
• @RavenDreamer As far as I can tell, this question is about the Flash Version Map Pack, which is actually a custom campaign for Portal, based on the Flash version made by the same people. – a cat Oct 23 '11 at 18:28
• @lunboks I'm counting rooms as they are separated by actual doors. – Iszi Oct 23 '11 at 19:32

It appears to be a couple of those "speedy thing goes in, speedy thing comes out" puzzles. This means you'll need to use your falling momentum to shoot you out of a wall, over a jump. Also notice that, in this video, the player crouches as they are flying through the air, presumably to make Chell more compact and therefore more likely to make the jumps.
