Neil, buddy, yes, ice expands with great force, but what Actually causes a lose to burst, or more often, a fitting, is the fact that water cannot be compressed. When you plug one end of a pipe (the shut off on your sink), it blocks the water from displacing the ice and the pressure formed therein will burst a fitting. Also, since the early '90's PEX is standard supply lines for all commercial and residential. Is incredible plastic. Check it out. Its in Your house... Love you man. Thanks for everything.

Another way the force of freezing water helps life; it breaks down mountains into dirt. Water in cracks freezes, fracturing the stone. More cracks and freezes, more gravel that tumbles down the river to become soil. Erosion would take so much longer if not for 'frost heave'.

So it made me think of a question for you. When it comes to the expansion of the Universe how do he know it is "Expanding" vs our Universe "Unwinding" ? It may seem we are expanding but we are in perception of the Universe time dilated vs. what came before the big bang.

The ice ball press unfortunately is just melting the ice from the conductive property of the metal which transfer heat into the ice, melting it. It doesn't work as well once the press becomes cold. So it's not the pressure that melts it. The pressure is from the weight of the press which is very small and the surface area are as big as the ice. So there isn't as much pressure than just heat transfer.

The skates melting ice to make it slippery is kind of a misconception, tho that does accour in some small way its usually not thought that this process makes ice slippery and allow skates to glide across it. Someone in flat shoes will experience the same lack of friction or slippery-ness, they will be dispersing thier weight over a much much greater area decreasing the pressure the ice is under. Even holding ice in your hand in 1 atmosphere/14.7psi ice is still slippery to the touch. Scientists are not 100% agreed on what makes ice slippery. I till love you guys neil is prob my favourite science communicator. Love the videos keeps me sane during lockdown.

I thought the glaciers on water melting made the levels rise because they are made out of fresh water, and the ocean is salt water, so they are pushed higher above sea level. Is this cancelled out by the fact that after they melt, the fresh water spills into the ocean and mixes with the higher density salt water?

I don't know for certain, but I suspect that copper is used to make the ice spheres due to two properties of copper. The first, and one I suspect is probably more likely, is that copper has one of the highest thermal conductivities of metals, the other is its anti-microbial properties. I believe copper is beaten out by silver in thermal conductivity, but silver costs more.

Yeah but if the ice melts off the land, then the land rebounds and gets higher. 3.98 degrees celsius is when water is most dense. Oh and I have skated at -20 and it is not as “slippery” as ice near freezing. At even lower temperatures cross country skis dont glide as well. Driving on -40 is slippery yes but not as slippery as driving on -5 ice. Life in Canada has proven that. So while the science of ice skating is not known perfectly it does require some melting of the top layer to create the slipperiness.

Once again I will guess before I watch the video. As water freezes it expands which increases the surface area while the mass remains a constant. Once it's frozen ice has less mass over a greater surface area which causes it to have less gravitational pull per unit square than water. Now I will watch your video.🍺

I clicked on this video because I wanted to know why ice floats. I was already aware that water has maximum density around 4 degrees C and that ice is approximately 9% less dense than that, and hence it floats, but that doesn’t help with why that is the case. What I wanted to understand is what is unique about water that causes it to exhibit this particular property. I did a bit of research and learned that: “Water is the only non-metallic substance that expands when it freezes.” So, that suggests that this property is an unusual one which further drives my curiosity as to why it is so. Any materials experts out there who looked into this a bit deeper that can explain why this is so? Thank you.
