Waiting for someone to point out that you don’t approach a vat or barrel of acid with bare hands or bare skin (even if you’re wearing googles). Amelia dropping things that close to the barrel is risking acid splash and that ain’t going to be fun for the skin. (Okay, I pointed it out!)
On pane 3, I wonder what that kid is carrying in that box, and why the other kid wants to burn a teddybear to a crisp in acid! Gah!
