Sound Is Just Wiggly Air Sweatshirt
"Hey buddy, what actually is sound?" Forget about compression and rarefaction, about transmission of energy through molecules that actually don’t travel anywhere themselves, carrier waves or kinetic to mechanical to electronic transduction... Give them the most simple, yet true answer there is: Sound is just wiggly air!
This design is also available on a short or long sleeve tee, tank top, hoodie, mug, mouse pad, gear bag, phone case, and a sticker! See them all here.
