When you squeeze the bottle, you are increasing the pressure on every part of the liquid inside which means that you are also increasing pressure on all the objects inside, including the dropper and the rubber bands. Squeezing hard enough will push up some more water inside the dropper. The air inside the dropper compresses slightly as more water is forced in. Since water is much denser than air and when more water enters the dropper, its overall density increases, making it heavier than when the pressure was not applied. That’s why it sinks. Release the bottle and the air inside it will expand and push out the extra water again, and the dropper will rise. By tilting the bottle sideways you can try to aim the dropper and the rubber bands into their respective goals.
