I filled 5 of them (the 1.5 gallon size) with sand, then topped that off with water to remove all the air. They weigh about 22-24# each. Makes great weights for the pool stairs when attached with cable ties.

If you live in a cold winter climate, Fill the bottles ( minus labels) about 1/2 full with gravel and cap tight (enough gravel so that just the cone top stays above water when submerged). they make great freeze gizmos (ice pressure absorbers) for your pool in the winter.
