So I was thinking how it was impossible to make a sand castle with multiple floors without it caving in. So I was hoping Notch or Jeb would think of a device for an upcoming update to make a switch to control the gravity influence on sand and gravel without hacking. I just want to make a 100% sand castle but I currently have to use wooden planks for my top floors. If you have the same problem, we should do something about this. Here is an example of my second story on my sand castle.
