Can you make a rocket engine using hydrogen peroxide and silver?

At a drag race, I once saw a rocket car that was supposedly powered by spraying hydrogen peroxide on a silver mesh. The resultant reaction produced huge amounts of pure white smoke and apparently enough thrust to propel the car rapidly down the track. Does hydrogen peroxide really react with silver that way?
