What To Do When On Blue Meteor?

So i solved all puzzles and came to blue meteor but i can't find what to do next, i just took shard and fell off..

People say i have to find a button and a water source block but i can't find it, i just keep getting glitched in glass blocks until i fall off meteor and then have to do all puzzles again to get to meteor only to fall off again..

Is there a single video that shows how to do it? All i've searched seem to fall off meteor.

 

go down meteor. button behind waterfall

 

Thanks, is this right when i jump off the big meteor? I'll try go there again soon

 

I found it! Thanks a lot!

It was just down the meteor, you have to jump on the tiny glass thing and click button, then fast jump inside and hope you don't get glitched on the glass lol, i got lucky
