Spoiler:

are you talking about the real life C-4 explosive? I was asking for the color of the bottle of "chem lab c-4". if it turned out that it was taken out of the lab, then somehow parts of it, if they are of the same color as the monobear display bottle, got mixed with the monobear bottle shards, it might explain the weight increase as pointed out in no. 22.
