i suppose this could also depend on the way the gellies were made.
Im no expert in this so i may be wrong but i can think of 2 different ways to do it.
1 would be mixing the LSD with the gelatin solution prior to pouring it into the light fixture that gives each hit that shape. Then waiting for it to dry and voila, the LSD is evenly distributed in all the hits.
or you could make the gelatin solution, pour in the light fixture and then dose each indivdual square with a drop from vial and then let it dry. This is less practical when making large amounts of hits, but would still work. And in this scenario the LSD is not evenly distributed and breaking it in half may not split the dose in 2 even halves.
Most likely though it was made the first way i described therefore breaking it in half should be fine.
These days any time im sitting in class or a buisness office and i look up at the flourescent light fixtures i always think, "Wow, that could make soooo many hits of acid."
