Exploration Stage: Burned-out Estate
From: Mr. Black
Description: I see. How can you stay away from fire at all? You must have used more flammable alternatives. You need to identify household items that could cause a fire. One such item is an iron. Please help us find it!
Completed: Oh my god! What is this? The coal in the iron has exploded and is giving off colorful sparks like fireworks. Eli, you said you don't use fire at home, but how do you heat the iron? The lid is blown off. Could the sparks have caused the fire?
