Thanks Bill! Miss ya man! Happy new year and best to you and the fam.

Thank you! I appreciate the encouragement.

You're welcome!

Glad I could help! Best wishes in your career!

As you go higher in the atmosphere it is cooler due to the lower pressure. So the ice at the top of the tank actually helps to mimic the cooler temperatures that would naturally be found at higher elevations above earths surface. This combined with the warmer temperature at the bottom of the tank (representing the surface of earth warmed by the sun) results in the convective process beginning.

Glad you enjoyed it!

Wow! Maybe he flew farther than I thought;)

Thanks! Glad you enjoyed it.

Glad to hear! Hope it went well.

I think it makes more sense when you think of the atmosphere as a giant dynamic fluid tank. What gets the high pressure zones started is falling denser air and what gets low pressure zones started is less dense rising air. However, as the warm air rises it begins to cool, condense and create cloud cover and possibly rain. These conditions often result in less sun and ultimately cooler surface temps. On the other hand the falling cooler air warms as it approaches the surface (check out adiabatic heating if you want to get into the nuts and bolts of this) and is generally less humid, resulting in clearer skies and ultimately solar heating of the surface. So the dynamic that got the whole convective cycle going has different outcomes or results than the initial cause would indicate. A final note is that it is true that pressure increases with lower altitude and decreases with higher altitude, but this is due to the weight of the atmosphere. However the unequal heating of the earth means that there will be "columns" of air that are relatively less or more dense due to differences in temperature. Hope this is clearer than mud:)

@christopherdever5536 Thanks! One last question. So according to this cycle and sea breeze model, when the pressure in the sea level is lower, in the atmosphere it's higher and the opposite(higher pressure on surface means lower pressure in the atmosphere). But we also know that lower pressure on the surface is connected with lower pressure in the atmosphere, so doesn't this also contradict the previous?

Glad I could help!

You are very welcome! Happy New Year to you.

Glad you like it!

Glad it helped!

Good point. Any bullet that travels faster than sound (which is most of them) will hit you without warning. Your best bet would be to react to the muzzle flash, but you still wouldn't be likely to dodge a bullet unless you were really far away and incredibly fast.

You are very welcome!

I've never worked on that. Sorry I can't be of more help.

Yeah I thought I could do this the easy way...only it wasn't the easy way. As for Mitchell - good question. I didn't have to. Good luck with your work. Bet you will get it done faster than I did.

Glad it helped! Thanks for the feedback.

Glad to help! Sometimes the simpler explanations are best.

I'm pretty sure it was supposed to be a direct replacement...not a very good direct replacement though.

Thank you! Cheers!

Awesome! That my friend is what it is all about!

Thanks!

Thank you! That is the challenge I always face with my young audience. I remade this video about 4 times to be sure my words wouldn't set my students up for later misconceptions.

Thank you. Cheers!

Agreed! That is what happens when you hand the camera to a student;) I remade this video so it wouldn't be so distracting. I think the link is in the description for my updated video - it may also show up in a card at the top of the screen near the beginning. Cheers!

Nope. Haven't had that problem yet;) Good luck!

Yeah, that manifold is a real pain.

Glad to help. I been there many times;)

Thank you! Cheers!

Thank you! It was a fun demonstration to make.

Thanks for the positive feedback. I have tried using a fish tank heater to be able to sustain the "updraft" a bit longer but it just didn't give off enough heat to do the job. If there was a way to use some kind of floating material instead of food coloring and a heater instead of a rock this could seriously lengthen the time the demo would work. Cheers!

That is super encouraging. Thank you for sharing!

Lol. Thanks though. Here is an updated version that is a little more refined and in depth. kzbin.info/www/bejne/gaGomYmbp7Jgr7s

Seriously! Just trying to give the real life experience of being in a middle school classroom;) Here is an updated version of this with a little more explanation and less student noise. kzbin.info/www/bejne/gaGomYmbp7Jgr7s

Thank you! Cheers to you in India.

Thank you.

Glad you liked it!

Sure thing. Hope it was helpful

Don't remember who said it first but happy to pass it along. Cheers!

Thank you! Cheers!

I know. It's almost like they tried to hide that feature.

Thank you! I appreciate you taking the time to let me know this is helping others learn. Stay curious my friend!

Thank you! Cheers!

Awesome! Miss you guys. Hope you are having a great start to your school year.

Honestly I'm not sure what kind of rock that was. I think I found it in my backyard. If I can locate it in my science lab storeroom I will try to identify it.
