That is correct. If attempting to replicate that demo, please do not eat the gummi worm after putting it in rubbing alcohol.

Thanks for the comment. I really hope you attempted to go see totality for yourself. There is no video on the internet that accurately depicts what you experience in-person when viewing a total solar eclipse. It is like nighttime in the middle of the day...yet, off in a distance it looks like twilight (truly hard to explain in text, and perhaps unexplainable...you have to experience it for yourself to truly appreciate it). You can actually see stars, planets, comets and galaxies in the daytime sky because it is that dark in the path of totality. But even in this video, you should notice that my very visible white t-shirt becomes invisible (i.e. too dark to be seen by my camera) as totality descends upon us. I have twice been "close to totality" (coverage 90% or greater both times) and it is very different than being in totality. Even during the total eclipse, in the seconds just before and just after totality, the sky is still pretty bright (which you hear me and another person mention just after totality in this video in real time). It is amazing how only a slight sliver of the sun being uncovered by the moon (i.e. 99% coverage) can cause such a bright sky. So no, being near totality is not like actually being in the path of totality. Lastly, when I viewed this total eclipse, totality lasted 2 and a half to 3 minutes. The 2024 totality was greater than 4 minutes for most folks. But really the darkness isn't about the length of time it takes to get dark, it's about the fact that the object giving us light (the sun) is completely blocked. Again, I hope you had the chance to check it out for yourself!

Thanks for the comment. Because the sun is partially blocked, the shadows that are produced look different. For example, in the part when we are looking at our hands, it looks like our hands are out of focus (in-person it was really obvious that our shadows were abnormal). Also, in the valleys between our fingers, there were strange, nub-like shadows visible. As the moon got closer to covering the sun, all the shadows on the ground through the tree leaves had a crescent shape to them. Admittedly, I had a low-grade camera, and it is not as obvious in the video as it was in-person.

You are so welcome!

No problem!

You are so welcome!

Thanks for the question. Even with the glasses on, it is still possible to look above or below the glasses at the sun. This means there is still the chance for eye damage. Adults and older children will know not to look above and below the glasses while looking at the sun, but younger children may not know better. Putting the plate around the glasses eliminates the possibility of peaking at the sun altogether (if done properly). The big idea being to prevent eye damage while still allowing even the smallest of children to enjoy the eclipse.

Glad you enjoyed it!

Glad I could help

This is a demonstration that teaches about observation, assumptions and definition.

Hey Dahlia...it's great to hear from you! I hope you continue to enjoy my videos!

Thanks for the question. Although the focus of this video is cohesion, both cohesion and adhesion are demonstrated in it. Cohesion is demonstrated by water connecting to water along the surface of the string and traveling down it in a “stream,” as explained in the video. What I neglected to point out in the video is that adhesion is demonstrated when the string is dipped in water (1:37 minute mark) prior to the attempt at getting water to travel down the string. Definitions for both cohesion and adhesion are given at the 0:45 minute mark.

Fair question. Just an oversight on my part. From the looks of it, the cold water was ~6 degrees Celsius, and the hot water was ~44 degrees Celsius.

Glad to hear that

I was very disappointed

Your latter point is the key. Cooling it from a localized area impacted what happened inside the thermometer. Had I heated/cooled it around its entire area in a uniform fashion, the time it took to warm it up/cool it down would have been impacted.

Glad it helped!

I appreciate that!

Thank you so much 😀

Thanks for the heads up!

Happy to help!
