Upwards slide

From Glitches

From the game Super Mario 64 DS for the Nintendo DS.

This has only been tried with Mario, but could work with other characters. Go to the Princess's Secret Slide and slide to the bottom, but don't get the star. When you get to the bottom, turn around and face towards the slide(you must be exactly straight) Run towards it and jump onto the slide. Don't press any buttons. If you did it correctly, Mario or whoever you have should go straight up the slide very slowly. Once you get to the turn, though, you will turn around and go back down.
