The Power of Science (
The battle for the Cave of Miracles rages on outside while Gen, Senku, and Chrome try making a new weapon of science. Chrome runs out, Gen attempting to stop him but Senku says to leave him be. While Chrome is out scavenging, Senku begins trying to make urea nitrate, a "crappy weapon" but better than nothing.
Meanwhile, Tsukasa and Hyoga beat down swathes of fighters, bolstering the morale of their side. Tsukasa destroys the shock cannon before they can use it again. Most of the fighters have been beaten down, even when they try attacking in groups.
Making the urea nitrate relies on chance, and Senku has terrible luck so it fails, but then Chrome brings a small amoutn of Sulfurina left over from the gun on their tank, giving them new weapon options. Adding soap and doing a few more steps, Senku creates nitroglycerine, an explosive. He needs a way to send it across the battlefield so it doesn't injure anyone, and Gen offers a paper airplane. Dripping some of the nitroglycerine on the tip of the plane, Senku throws it. It lands on the far end of the clearing, exploding.
