Hashtag powered contraptions? Cool! Hashtag powered contraptions made for adorable doggies? AWESOME!
GranataPet, makers of healthy dog food, set up fetching stations in parks across Germany that encouraged dog owners to check in with the hashtag #Snackball. Once checked in, the contraption threw a ball to their dog, and if the ball was returned in a certain timeframe, the dog was rewarded with a healthy snack.
