I had an eventful day in Chem today. I accidentally dropped the top to the crucible a few times, then when we heated it part of it cracked and flew off. I hope that wasn’t due to my dropping it. After it was heated, I carefully and firmly picked up the top with the tongs, and one arm of the tongs slipped over the other, flipping the top and knocking over the crucible, spilling the barium chloride all over the table. Oops. Justin and I had to get our data elsewhere. 🙁
