While the images of carbonated mineral water are highly informative, note that even 'still water' can have a lot of dissolved gas (air)... -

This is no paradox, it is standard experimental science. Well-considered and carefully-executed controls are critical to good... -

Indeed - it's a data point suggesting that water expands when it freezes. The density of ice in the bottle is lower than water, and... -
FactChecker replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.I don't expect "infinite controls". I would just encourage you to be reasonably careful about your experiment before you expect good... -
FactChecker replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.Good point. That makes the measurement of weight that others have recommended more important I can't judge the volume of the collapsed... -

A simple controlled procedure to remove thermal contraction as a confounding factor: 1. Fill the bottle completely to the brim with... -

If I were observing volume changes of a plastic bottle, I would, measure the mass before and after by placing the bottle on a kitchen... -

When a plastic bottle collapses in one direction, it gets larger in another, creating an elliptical cross section or even more crumpled... -
FactChecker replied to the thread Undergrad Is Water's Volume Expansion Upon Freezing an Intrinsic Property?.Some of those photos show a LOT of loss of volume. IMO, that much shrinkage is hard to explain. And it is very pronounced in some... -

Informative.
The volume expansion from water to ice is an intrinsic property of water specifically under the constraint of negligible confining... -

I froze a plastic bottle full of water (as near to mo air as I could manage) and put it in a bowl of water. It floated: And a crop of... -
FactChecker replied to the thread A question about quantum entanglement.IMO, you are putting words into my mouth. I reasonably thought that we were discussing the SR theory of what is happening now, locally... -

@LightningInAJar , doesn't @Filip Larsen 's post #8 give you everything you've asked for? -
FactChecker replied to the thread A question about quantum entanglement.Mathematically, with very reasonable/desirable assumptions, there are only two possibilities, and only one with a constant speed of... -
FactChecker replied to the thread High School Good drawing of Earth's orbit for model? Possibly vector file?."Perfect" is a very strong requirement. The Earth/Moon combination is nearly perfect. The Earth alone will be influenced a tiny bit by...
