Why cannot the wave nature of microscopic bodies be observed?

The wave nature of microscopic bodies cannot be observed . If we use heisenberg's uncerainity principle we know that we have a fixed bound for product of errors in position and momentum. So if we try to calculate he position too precisely then we have a large error in momentum and are not able to measure it. If we try too measure velocity too precisely than we have a large error in position. Thus we are not able to measure the wave nature of microscopic bodies.
