Yea, when you put one of them to working on fixing the wall, you have to just sit there and watch them. As soon as they want to do something else, pick them up and drop them back on the bucket again. It goes a LOT faster if you have more than one working on it at the same time. But you will still have to sit and watch and keep putting them back on the job until it's done. After a while you will see a difference and when it's completely done the bucket will disappear. I haven't ever had a bucket dry up yet doing it this way, but I knew it did cause of reading it on these boards.
Oh, and don't forget that kids 14 on up can also help with that job. One time I had a family that still had the 18 year old kid at home and then also had 14 year old triplets. I didn't even have to have the parents do it at all, I just put all the kids to work and kept putting them back when they tried to run off and it was done in no time!
