This mod adds throwable floppies to Minetest... That's what they're used for right?
The floppies can be crafted with 7 wool nodes in a H-shape, a steel/iron ingot at the top and paper at the bottom. Red, green and blue floppies exist, craftable with the equivalent wool in Minetest Game.
They're not only for throwing!
Minetest how-to-fly guide number 2 (the floppy edition).
Step 1: Find (steal) floppies. Minetest bro tip: install ROllerozxa's floppy mod for faster acquiring of throwable floppies. Step 2: Use mese magnets to collect all of the floppies and gather them in your hotbar. Step 3: Gain some velocity using mese thrusters. Step 4: Start throwing floppies in the direction of your free flight, tilted downwards by approximately 45 degrees. Step 5: Jump. Step 6: Successfully fly. Step 7: Lose focus and (also successfully) crash and break every single bone in your body and turn your innards into (some) delicious mince.
don't think it's a serious mod, but I like it.
