Hello everyone!

As some of you may know, there has been a discovery on Roo's Tubes where you kind-of bonk into the wall and get a huge chunk of speed from it.

I've been investigating this and I think I now know how it works.

I've tried to sum it up in this clip while showing an example on Hyper Spaceway:

I'll type it out here again:

What I think is happening there is that when you jump in an area with a tube-like ceiling, and you hit the ceiling (NOT the wall!), it will push you down and give you a huge speed boost. You can maintain the boost as known with boosting, BUT you will lose it as soon as you get ANY airtime!

So a fairly reliable way to do this is to hug the wall, get to a big jump, steer slightly towards the wall so you hit the ceiling, then use the hop boost and the single power slide you have to maintain the speed as long as possible while avoiding to become airborne.

I found this method to work quite well, and I even discovered a new spot for this on Sewer Speedway:

I wasn't able to find more locations for this so far, and I'm not sure if it works on regular ceilings as well. But with this knowledge, it might be worth to investigate most of the tracks for similar abusable sections ^^
