LSD
crystal is almost always diluted into liquid before consumption. For ease of distribution, the liquid is put into dropper bottles. One drop is measured out to be
one dose when making the liquid.
In a dropper bottle, the glass dropper tube can hold dozens of drops at a time. The doser carefully squeezes the dropper bulb so that it only pushes the desired dosage out of the tip, say
1-5 drops.
LSD liquid is often dropped onto or under a persons tongue.
People can feel the drop in their mouth but just barely.
Puddling is when the doser does a forceful squeeze of the dropper bulb which results in the dosee getting a larger than normal amount of liquid in their mouth, which looks and feels
like a puddle.
Sometimes it’s intended sometimes it’s not.
