Laser Synthitar: Man’s Weapon Against Sharks With Laser Beams

A shark with a laser beam is a pretty freaking deadly animal—so we understand. No one has lived to tell the tale. But when these sharks finally attack Man in mass, we’ll have a plan.

That plan is called the Laser Synthitar. The DIY project combines a broken guitar (thought useless!) with three standard laser pointers (thought boring!) and a sound modulation system (thought deafening!). Combined, these technologies form the most promising defence against sharks with laser beams. But even if we still fall to the techno-aquatic beast, we’ll do so while rocking.
