Good Morning @MLGRuY6s, it’s in the description. Good Morning @MLGRuY6s, here it is 3 flashlights Blue, Green and Red from Amazon amzn.to/4bj7yX5 Thx Ken

@KidsFunScience Oh, my bad. Thanks a lot for responding!

@@MLGRuY6Syour welcome. Thx

Good Morning @DarlineshaneSim, I used 2%. Everything is listed in the description. Thanks Ken

Good Morning @miguelcervantes4705, you’re welcome. I haven’t seen StarTalk before. Is it a KZbin channel? Thanks Ken

Same… I needed to see more explained on this

@@KidsFunScienceit’s a KZbin channel featuring Neil DeGrasse Tyson… well I believe it is his KZbin channel sorry lol

Good Morning @@anthonyrhodes840 , No worries. I just found it. Very cool. I'm glad you found me and were able to do this trick. Thanks for letting me know. Cheers! Ken

Hi @Deny-Swqp2, 15 seconds on average, but I had one go for around 25 seconds. If you try let me know how long you’re lasted. Thanks Ken

Good Morning Michelle, Thank you as this was fun to do. I need to try Lifesavers next. : )

Good Morning @dserojales, I just used masking tape and taped the positive side to the negative.Make sure they are touching together. So I stacked mine upright so the battery was ontop of the other battery when I taped it. I found when laying them down they seem to separate just a little. Thanks for watching Ken

Good afternoon to you.

Good Morning @radeking4318, Its not lead, but graphite, which itself is not inherently dangerous, when used to create a light bulb with batteries, the main concern is the heat generated by the electrical current passing through it, which can become very hot and cause burns if handled improperly; therefore, proper safety precautions like gloves and heat-resistant materials should always be used when conducting this experiment.

Good Morning @stephanien6237, Yes it sometimes takes a day or 2 depending how thick the glue is, but it will harden. Thanks Ken

Good Morning @williamcousert, Great question and I have never tried and don't know. But now I want to try it. If you try it please let me know the results. thanks Ken

Good Morning @shibolinemress8913, Good question. I don't know as I have always just used food coloring. I would assume it would work. If you try it please let me know your results. thanks Ken

@KidsFunScience I did try candle dye, and the results were interesting. The colours were more muted and didn't spread as quickly. At first I thought nothing was happening, but after a while I did get some interesting shapes. But for explosions of vibrant colour, food dye is the way to go.

Good Morning : )

Good Morning Mario, yes when I have dropped them some broke in half and some nothing happened. Hitting them usually broke. But only tried a couple times. Have you and what was your results? Thx Ken

Good Morning Reb-y2p, great question as I have not tried and do not know? If you find out please reply and let me know. Thanks Ken

thanks for watching.

@KidsFunScience your welcome 🙏

Good Morning @chuckwieser7622, Your welcome. Me and my son had such a good time trying this. Even though our bridge wasn't the most structural, it worked. : ) I'm sure a few soldiers would shake my bridge apart. Thanks Ken

Good Morning @generallee014, Unfortunately I do not. If you find any let me know? thanks Ken

Good Morning @michaelturner4457, These are very cool and I was sad when they stopped making them. I hadn't heard of those, but I had I love science. : ) thanks for sharing. Let me know if you know where to buy any? thx Ken

Good Morning @PeterBerta-bz2on, Your welcome. I love this one. thanks Ken

TV works the same. It's about light waves. White and Black can be made by having various amounts of Red, Green and Blue. All Red, Green and Blue for full white, and no RGB for black. With a TV camera, the colour controls are Red Green and Blue. The 3 colours we see behind the pen are the colours that are created by removing red, green or blue. Removing Blue (so only Red and Green) will give you Yellow, removing Red will give you Cyan and removing Green will give you Magenta. The cameras have to be 'lined up' before using so the RGB levels are set right so the camera will represent the light that the lens picks up as true white and black.

Good Morning @marcieuzomah, It is just regular printer paper. Let me know if you give it a try? thanks Ken

Good Morning @LTWGaming12 , Mine kept falling also. I had to keep bending the wire to get the right balance. Once I had the right balance it works every time. It takes patience. : ) thanks Ken

Good Morning @willistisdale4293, I run Science Nights and assemblies and most times adults are having more fun doing the experiments. I know I love them. thanks Ken

Good Morning @555madeinindia, Yes this is a fun experiment. you are welcome.

Good Morning @jailisban5981, I just use the 8 D batteries, some people say you can use less, but I have not tried less batteries yet. I believe every D battery is 1.5 volts. I hope this helps. Let me know if you can do it with less batteries. thanks Ken

Good Morning @powder1234, That is great, what was the overall reaction in the classroom? Are you in San Francisco? thanks Ken

Good Morning @sarahisdope, Very cool, I might have to try that one day. Thank you for sharing. thanks KEn

Not sure as I haven’t tried copper before. If you try let me know. Thx Ken
