I just tried it again (Shift and right clicking with the hopper in hand) and it didn't work. When I created the world I accidentally chose creative mode so I opened it to a LAN map and switched it to survival with no cheats. Is this maybe why it doesn't want to work?
Edit: I started a new map as survival (allow cheats ON) and it works just fine. I guess it has something to do with creative or maybe LAN maps?
