There was a lady who tried that, bringing a bottle of frozen water and claiming that ice is not a liquid. I don't remember if she was allowed through or not, but looking it up, apparently it works now:
> Frozen liquid items are allowed through the checkpoint as long as they are frozen solid when presented for screening. If frozen liquid items are partially melted, slushy, or have any liquid at the bottom of the container, they must meet 3-1-1 liquids requirements.
I’m not sure how making a bomb out of liquids works, but could you not just freeze all the necessary liquids and then hit them with the hand dryer in the bathroom?
Why not sell fresh squeezed juices right as people get out of the security?
