This general audience talk will discuss the High Altitude Water Cherenkov (HAWC) experiment is currently under construction at Sierra Negra, Mexico and consists of a 22,500 square meter area of water tanks instrumented with light-sensitive photo-multiplier tubes. The experiment is used to detect energetic secondary particles reaching the ground when a 50 GeV to 100 TeV cosmic ray or gamma ray interacts in the atmosphere above the experiment. HAWC complements existing Imaging Atmospheric Cherenkov Telescopes (IACTs) and space-based gamma-ray telescopes with its extreme high-energy reach and its large field-of-view. The HAWC instrument will be used to study particle acceleration in astrophysical sources as well as search for more exotic phenomena such as dark matter annihilation and primordial black holes. I will present an overview of how HAWC works and what we hope to accomplish over the next few years.
