Sink in "quicksand"?

[Sordrin]

I am attempting to create a quicksand pit, and in previous versions of mc, a bunch of cobweb under blocks with a simple detect and tp down one block would cut it.

Now the player simply starts swimming in the cobwebs instead of suffocating in the block above it. Not quite the effect I am going for...

So, I am looking to skript to try and find a solution, but try as I may with any combination of tps, slow falling potion effects, push player commands, gravity changes, etc, I just can't seem to get a nice smooth sink and suffocate.

Any ideas?
Thanks.

U can also try some realy high levetatation values u got to find the right one but i believe if u find the sweet spot it will give u a prefect slow falling.
