AddUseItemCallback("", "chemical_container_epoxy_1", "acid_container_1", "pickacid", true);
}

void pickacid(string &in asItem, string &in asEntity)
{
RemoveItem("chemical_container_epoxy_1");
GiveItem("", "chemical_container_full_1", "", "chemical_container_full.tga", 1.0f);
PlaySoundAtEntity("", "puzzle_acid_success.snt", "Player", 0, false);
