Hi. I was wonerin' if you could give a easy experiment that proves that sound travels faster in a solid than in a liquide or gass...  
many thanks

If you have fancy measurement equipment, you can glue microphones onto a stick of wood and a stick of metal.  Whack them with a hammer and connect your measurement equipment.

Without fancy equipment, here are some ideas

If you live near a railroad track, you can go to the track with a friend and a pair of binoculars.  Have the friend stand about 1/2 km down the track and hit the track with a hammer.  You will have your hand on the rail and will feel the impulse if the tracks are welded.  You will also see through the binoculars when he hits the rail.
