i will some a kind of funnel and echo chamber, and huge amplification equipment, with speakers pointing outside the windows of the bus.
therefore, this can amplify any resonance and boingy wobble board rolf harris sounds from the metal panels to around 2000 dB, surely enough to shatter the windows of passing cars and fine bone china.
i am planning on unveiling my creation soon on a local tour de force, on 12am on a sunday night coming soon ..
