Biggest explosion+Slowness walk

Command for explosion:
/summon Creeper ~ ~ ~ {Fuse:0,ExplosionRadius:127.9,powered:1}
Oh yeah, and don't do it on your favorite world, I say!
How to do the slowness walk:
---WEB---
---WEB---
---SOUL SAND---
---PACKED ICE---
About the packed ice, don't do it normal ice. I found it that if you're puting packed ice under the soul sand, its more slow then normal ice.
And about the player in the slowness walk:
- Slowness effect level 5
- Sneaking
- Holding an accident bow without shooting
And by the way, the biggest explosion isn't going to crash your game.
