When flying at a high speed into a honey block, The player can swim in the first pixels on all sides of the honey block. This was found on a server. The player in first person appears to be standing, floating on air. To others and to 2nd and 3rd P.O.V, the player is swimming, as if in the air. Goes away as soon as you walk away from the honey,

Swimming Inside Honey Blocks

This is MC-147612 and intended. The hitbox of honey blocks is actually only 14x14x14 pixels (the more opaque block visible inside of the honey block), so you can partially move inside of the block (which is what you do when you slide down some honey blocks). Since slime blocks are full blocks however (16x16x16 pixels), there is actually a 1 block tall space between the upper and the lower slime block, in which you can crawl.
