This is the supervillian's plan, coupled with a reagent that reacts to filtered light, in the Batman comic Messiah of the Crimson Sun.Rimuru used countless water elementals to focus and refract light into a multitude of lethal beams that were capable of decimating an entire army with Ludicrous Precision. The spell Megiddo from That Time I Got Reincarnated as a Slime is a Beam Spam version of this trope.Yuuko has them guess which hand she has the eraser in, and after a few missteps Mai pulls out a magnifying glass to burn the back of Yuuko's hand, which she promptly declares as cheating. Nichijou in one scene, Mai and Mio ask Yuuko if they can borrow her eraser.A filler villain in Naruto had the ability to create a giant lens to fry people with.Mobile Suit Gundam 0083: Stardust Memory introduces the Solar System II, which is much more efficient thanks to better materials and targeting software, meaning it can achieve the same destructive power with only 408,000 mirrors. In this case it's somewhat more plausible, because the array consists of four million mirrors, each the size of a small building, and they're all aimed by computers. Mobile Suit Gundam has the Solar System, a superweapon wielded by The Federation that is a scaled-up version of the old Archimedes "Death Ray".And then they mock him by dancing in front of him. Golden Wind has a sequence where the protagonists, during a Jack Bauer Interrogation, use a pair of glasses to focus the sun's rays right on his eyeball.He ends up blaming Josuke for it because they were gambling at the time and Rohan was so fixated on finding out how Josuke was cheating that he didn't notice the fire until a third party pointed it out. An unintentional version happens in Diamond is Unbreakable, where Rohan leaves a magnifying glass on a newspaper and ends up starting a fire that does quite a bit of damage to his house.Caesar Zeppeli uses bubbles to reflect light from outside a castle to the inside at Wamuu, allowing the light to penetrate him.The Stone can also be used to power up the Stone Mask to turn a Pillar Man into the Ultimate Lifeform. It thus can also amplify the Ripple, which is basically solar energy generated by humans. The Red Stone of Aja, when put up to a light source, will cause it to reflect the light a million times and emit it out the opposite side as a laser.There is also a traditional example, from a flashback featuring Senku doing this as a child.The plan works perfectly because Magma buys the bluff completely and because Chrome's dedication to saving the woman he loves allows him to stay stock-still and keep the water "lens" from breaking. Likewise Magma needs to be held in place for 60 seconds, so Gen claims that he cast a spell that will make Magma's heart explode if he moves a muscle, adding that he can only maintain the spell for one minute. It takes a massive string of contrivances to work - since eyeglass lenses are concave, Chrome has to fill them with his own sweat and tears to create a convex lens, then hold absolutely still to keep from disturbing the surface of the water. Chrome ends up faced off against Magma and has no hope of winning in a straight fight, so he uses a pair of glasses that were left on the arena floor to try and light Magma's clothes on fire. Stone features possibly the most badass instance of this trope during the Tournament Arc. He summons a giant lens and use it to fire an extremely hot sunbeam. Used by Nova Shenron in Dragon Ball GT.She stops just short of melting the ship. Marika reconfigures the solar sails to reflect Tau Ceti's sunlight directly onto the pirate ship, blinding their spotter and heating the hull. In Bodacious Space Pirates, the Odette II is being fired upon by a pirate ship using optical targeting.(Sadly, MythBusters tested this example of the trope three times and found it less-than-effective.) Supposedly, he focused the rays of the sun using an array of polished shields, mirrors, or lenses. Many attempts at this both fictional and real are inspired by the story that the ancient Greek scientist and engineer Archimedes used this sort of contrivance to destroy a Roman fleet during the 214-212 BCE Siege of Syracuse. In some cases, a larger lens may be used as an Improvised Weapon. On the other hand, sometimes children who do this are just portrayed as scientifically curious. At times this may be used to demonstrate that the child is an Enfant Terrible, or (in works written from the perspective of the insect) that Humans Are Cthulhu. This may take a few different forms.Ĭhildren at play may experiment with using setting fires or killing small insects with a magnifying glass. Someone uses a magnifying glass or similar optical instrument to concentrate sunlight to kill, burn, or melt something.
