Fungus analysis reveals Martian terraforming

The Doctor’s measuring glass is a critical tool in the experiment, used to pour a precise mixture of corrosive acids—sulfuric, hydrochloric, and acetic—onto the expanding fungus bubble. The glass tilts carefully over the sample, its contents reacting violently as the acids hiss and foam, nearly causing an explosion. The reaction shrinks the fungus, demonstrating the acids’ potency as a countermeasure. The glass’s clear walls reveal the bubbling chaos of the experiment, its lab-worn surface a testament to prior scientific trials.

Before: Filled with a mixture of corrosive acids, placed on Eldred’s laboratory bench and ready for use. The glass is intact, its contents stable but highly reactive.

After: Empty, its contents poured onto the fungus sample. The glass is now clean of acids, though its exterior may bear traces of the reaction. It remains a functional tool in Eldred’s laboratory, available for future experiments.

Doctor neutralizes fungus with acid

The Doctor’s measuring glass, used to pour the acid mixture onto the fungal sample, is a critical tool in the experiment’s execution. Its large size allows for a precise but swift delivery of the reagents, and its clear walls enable the Doctor to monitor the reaction in real time. The glass’s sturdy construction withstands the violent foaming, and its etched surface—likely worn from prior experiments—symbolizes the lab’s history of high-stakes scientific work. The Doctor’s use of the glass underscores his adaptability, turning everyday lab equipment into a weapon against the Martian threat.

Before: Filled with the pre-mixed acid solution, placed on the lab bench near the microscope. Its measurements are precise, reflecting Eldred’s meticulous lab practices.

After: Empty after pouring its contents onto the sample. The glass’s structural integrity is intact, though it may bear new chemical residue from the reaction.
