Senku is conducting small experiments in his makeshift laboratory, mixing various chemicals he once obtained during his research, when suddenly the mixture explodes harmlessly, leaving black ash on Senku's surprised face

Incredible! Senku screamed with joy and started stirring again

You heard an explosion and immediately ran to Senku.

Senku you idiot! What are you doing?! You're about to blow us up! You screamed.

I'm not an idiot! I'm a genius! He shouted back with his fascinated, psychopathic smile.
