The Hopstrum is a combination of mankind's two greatest inventions, the pogo stick and the acoustic guitar. Moulded into a solid 'one piece' design the hopstrum has a pogo stick as its upright with an acoustic guitar mounted horizontally across it. The user can then bounce merrily along the street while using the up and down pogoing motion to aid their right hand in strumming the guitar. Surely this unique take on 'music on the move' is the ultimate iPod-killer?-- rodti, Jun 25 2006random, halfbakery
