Great job teaching the kids. The flaming grape was a very nice touch! I'm 47 and still playing with lenses, telescopes and pinhole cameras.

The world needs more people like THIS guy!

This guy knows how to connect with kids really well. Great work

2122 views and only 4 comments? That is horrible. I think this video was done quite nicely and I would like to say thank you for posting it. I would also like to thank the gentleman who starred in it. He did a great job keeping the kids' attention. That is a monumental task in and of itself. But, to say it again, very nice video and thank to whomever posted it. Children are hungry for knowledge and science always fascinates them and sadly, times have changed and not as much emphasis is there.

Thank you for your dun and informative video. With the 8/21/17 eclipse coming soon, my 9 year old son has lots of questions. We watched your video together and he was glued all the way through. Thanks again for sharing.

When you add fun science into learning like this, kids are intrigued and soak it up like a sponge. It's soo important for them to learn about safety like protecting their eyes as it's not something you instinctively know, so they look up to responsible adults like this to know more about the world we live in, and precautions to take to preserve their eye's and health to live to a ripe old age! Some other video is showing how to smoke glass, very bad idea as it filters out very little UV rays and makes pupils open up larger letting in more damaging rays.. tutt tut!

Great job. Kids were engaged and for sure they learned something new. Thank you

loved the grape experiment! True, the Sun is an amazing creation of God. Without it the earth could not support life. Good info.

This is just beautiful. What a wonderful science teacher.

cool guy

Cool. I made a similar one out of a frosted mini wheats box. We are viewing from the band of totality in Georgia.

I miss being a kid, when everything was so new and amazing. It's like when people reach a certain age they think they know everything and that's that. We can learn as much from children and their curiosity as they can learn from us adults.

excelente vídeo!

Today's kids think they're harry potter or a pokemon or some type of wizard from some game / show / app.

Good lesson on viewing the sun through a telescope;-)

Cool vid on a hot topic.

Lol I was going to make this EXACT THING at 4:13 XD. I didn't know if it was going to work but thank goodness that it will!!

OOOooh! I see what you did there.

Its called a Fresnel Lens. Just google it, there are a ton of different sizes.

nice :)

2:12 where can i get big lens like this ? or what is it called, what brand : D ?

The link at the end is now bogus.

Nerd alert.
