Quicksand should be a viscous liquid.

Quicksand smelts to sand

Sand + water = quicksand.

Concrete from Quicksand

1. Gather quicksand in a bucket
2. Craft "Uncooked QuickStone" by adding 8 water buckets...
3. Cook Uncooked QuickStone bucket to get QuickStone powder...which also doubles as dark grey dye in a pinch
4. Mix QuickStone powder in a bucket with some water to produce a bucket of QuickStone
5. Pour QuickStone where you want it...wait for it to set

I like this. Defiantly adds interest to a previously annoying and dangerous block.

Like the idea could be fun to play around with especially in trapping mobs LOLZ!

No more Enderman killing traps? Would it be possible to craft a bucket of liquid quicksand with a block of sand to get the blocks we have now?

The current blocks would not change.

I came back because I just got what you were concerned about. I'll see what I can do

Quicksand will be looked at as we revamp existing biomes.
