First is with 20 lbs hanging ballast.

And as seen from the water.

This is with a second bucket underwater. Provides more inertia from the water. There are 4 ropes connecting the two buckets. Idea is the weights and ropes keep the bottom bucket upright and the 4 ropes keep the top bucket at the same orientation as the bottom bucket. Also, if we had slip-forms to make one concrete cylinder for the top, making a second for the bottom might not be too costly. This seems to work better than simple 20 lbs ballast.

Double bucket with weight on top (I think 5 lbs but maybe 2.5 lbs).

This next video shows the underwater view of a hanging ballast experiment. This is with 2 steel weights of 10 lbs each.

This video shows some dry land testing. First I just swing it like it swung in the water. Next we balance it on a bar and see how much weight on a side it takes to tip it. Then we try 4 separate 5 lbs weights (so same total of 20 lbs). This is not stable at all and can not even balance the bucket.
