This shirt visualizes meteor strikes in real time. It houses a microcontroller that wirelessly connects to Live Meteors, a database that detects meteor strikes via radio wave reflections. Each time a meteor is detected, the microcontroller tells the Neopixels (a type of LED) that are scattered across the shirt to light up. The longer the lights continue to flash across the shirt, the larger the meteor strike. This shirt is fully functional, washable and features a rechargeable battery. As long as your phone is nearby, you can visualize meteors anywhere!
how does this work?
When a meteor enters the Earth's upper atmosphere it excites the air molecules, producing a streak of light and leaving a trail of ionization (an elongated paraboloid) behind it tens of kilometers long. This ionized trail may persist for less than 1 second up to several minutes, occasionally. Occurring at heights of about 85 to 105 km (50-65 miles), this trail is capable of reflecting radio waves from transmitters located on the ground, similar to light reflecting from a mirrored surface. Meteor radio wave reflections are also called meteor echoes, or pings.
