  there is a track which is 50 cm long and 20 cm thick.. at the end of this track there is an elevated track having length 30cm and height 10cm.. At his height dere is a hole.. the challenge is to put the ping pong ball in the hole.. using steps utilizing different energies like mech, elctrical, sound etc..
  one such step can be dominoes or it can be rotating a fan with a motor which pushes a ball or sumthng..
  actually i want to get simple ideas on how to convert differnt energies into one another.. and some simple steps which can trigger the next steps.. the task is to be completed in 15-20 steps..

  I was a regular participant of contraption event a few years back when I was @ NIT, Nagpur.
  
  Use simple ideas and more steps, try more energy conversion and explain everystep in terms of energy conversion only. This is the only magic behind winningthe contraption events.
  
  Some basic ideas I used.
  
  1. Used a pile of cassets which was hit using a pendulam which was released after burning its thread from a candle,
  
  2. Used a motor/rotating fan which was started by completing the connection (I completed the connecting using water at my time.)
  
  3. Used a pump system to roll a ball
  
  4. Used sound (sound of song from computer, from this step I started my contraption.) sensor which completed the circuit and initiated my contraption.
  
  Arrange a few steps from the above list add a few from your ideas and you are good to go.
