Cork, A Micro Bluetooth Speaker That Sits on Top of Empty Beer or Liquor Bottles to Amplify the Sound
Leedeyeon created the Cork, a micro Bluetooth speaker that sits on top of empty beer and liquor bottles to amplify the sound. The sound boost of the Cork varies with the size and shape of the bottle used. The Cork started its life as a project on Kickstarter and is currently available to purchase from The Ggumim.
