They kept trying but kept hitting against the top. With time the grasshoppers learnt to leap to a height that corresponded to the height of the container. This habit served them well. It saved them the pain of having to hit against the lead. 

After a while the scientists removed the lead. To their amazement the grasshoppers had become dysfunctional. Although there was no lead to stop them the grasshoppers kept leaping just to the same height as they used to do when the lead was on. In essence the grasshoppers had developed a handicap which limited them to the previously prescribed height.
