A ballast is heavy weights or sand bags to stabilize a ship or air balloon while an anchor is weight that holds the ship or air balloon to float away
Think like this if you but sand in a bucket with a balloon in the bottom will the balloon be crushed? its the same way with water or any liquid the deeper you go the more of the liquid is pushing down on you which makes pressure rise.
I think it drops the ballast (sand filled bags) which are attached to the basket

Dump it in water. Pepper floats, sand sinks. This works but you can also try using a balloon. Fill the balloon with air then rub it on your hair. Then move it around slowly over the mixture the pepper will cling to the balloon and the sand will not.
