Let's Glitch Pokémon Yellow Part 18: Item Underflow Glitch and Celadon Looping Map Trick

Ever wanted to use all of the glitch items in Pokémon Yellow? The Celadon Looping Map Trick is all you need! and a tossable item like X special is optimal for the trick

However, any tossable items will work for the Dry Underflow Glitch. To clarify, it is called the "Dry" underflow glitch because it doesn't use fresh water. "Underflow" because the removal of the 1st item and the 255 stack item (that replaces the 1st item) creates an underflow in the item bag (roughly). That leads to an expanded item bag that can be accessed after giving a drink or fossil away.

CORRECTION: the method shown in the video is a form of item underflow that involves the removal of an item by a NPC (the fossils). Dry underflow avoids the use of a NPC entirely.

I may show a vid in the future to help further clarify the Dry Underflow Glitch and its variations.
