My friend showed me with this many, so that is what I have always used. How many do you use? Thx

Email me a short video so I can see what you are doing wrong. It works at all my science school assemblies. I will help you to get it to work. Thanks

I pour liquid back in to bottle and styrofoam will harden.

Made a mistake. Thanks for pointing that out. Thx

Good question. You can try a static sheet you use in the dryer. That might work. Great a static charge on a balloon and touch the static balloon to the tube. If you can get it to remove let me know how. Thx Ken

I believe I bought one can, but only used a little over one can. Thx

WOW they did take it up a notch. Thank you for sharing. Do they have a link to it? thanks Ken

Good Morning @byzidlatifi, Thank you : )

First it would depend on the shape of the ice berg. Assuming it’s also the shape of Empire State Building. That means it will be very tall. The upper portions will have a negligible melt rate (at least at first). The lower portions will begin melting quickly, but will soon slow down. Even though the ground near the ice mountain is hot initially, it will cool down pretty rapidly as the ice absorbs all the ambient heat. In addition, the reflectivity of the ice will actually reduce the amount of solar heat being absorbed in the area. Over time the ice berg will change shape, due to the base melting much faster than the top. Eventually it will become unstable, and you’ll get a massive ice quake that topples the mountain (or at least a large part of it). That would be an amazing sight! The parts that fell off would then melt much faster after landing on the hot ground. Empire State Building is 1250 ft and High temperatures, glacier ice melts at a rate somewhere between 8-15 feet per day. So a guess would be 83 to 156 days, but once it fell over probably faster.

Good Morning, I have never seen that before. How old is your candy? What brand are you using? Thx

Good Morning, lol it does look bad, but it’s good as it’s just frozen water from the bottle. Thx

Good Morning @noammor5878, I believe I was using a 10 gallon (37.85 liters) tank and filled it 2/3rds full. So I would guess around 7 gallons (26.5 liters) of water. Sorry for not listing this. Let me know if it works? thanks Ken

Good Morning @Baconithappen, I would say you are amazing. That is great that you can see both. Thanks for sharing and watching. Thanks Ken

Good Morning @JeromeKJB, great question and I’m not sure. If you find out please let me know. Thanks

Good Morning @kattycontrerascrespp564, Hello and thanks for watching. Have a great day. Cheers! Thx Ken

Good Morning @madriagajanjosephg.8047, thank you as this is a fun experiment I do at my science nights. thanks for watching. Thanks Ken

Good Morning @zzes9561, The USDA says, An egg can float in water when its air cell has enlarged sufficiently to keep it buoyant. This means the egg is old, but it may be perfectly safe to use. Crack the egg into a bowl and examine it for an off-odor or unusable appearance before deciding to use or discard it. A spoiled egg will have an unpleasant odor when you break open the shell, either when raw or cooked. thanks Ken

Good Morning @orelliscanada3121, yes and I do this one at my science nights and students love it. Fun and easy. thanks for watching. thx Ken

Good Morning @BernardThomas-lx1eu, thank you. This experiment I do with my neighbor kids every year. thanks for watching.

Good Morning @mavybigcas28, yes this experiment is fun and easy. I have done it at my science nights and the students love it. What other experiments is the Naga city Montessori doing? Thanks for watching.

Good morning @lomrust same here. Science is so cool. Thanks

☠️

Same here. Thanks

Yes, I have done this before at a science night and will try to post it on Friday. Thanks for watching and for the suggestion. Cheers! Thx Ken

Good Morning @user-pu2mx8jf9z, Sorry but I only check comments once a week. I hope you were able to find the information you needed. This info below was in the details on this experiment. Now I blew up a balloon, and rubbed it across my hair (freshly washed hair works best). Now we have a negatively charged the balloon. You can test your balloon by seeing if it will raise the hairs on your arm, if it can then your ready. If not rub the balloon more on your hair. If you don’t want to rub it on your hair, try your dog they love it. With my balloon negatively charged and bring it closer to the cup..... The toothpick moves. The positively centered toothpick is attracted to the negatively charged balloon, which makes the toothpick rotate and swing atop the coin!

Good Morning @DomenicOortiz, Thank you and I hope you did great in your science project. Thanks for watching Thanks Ken

You're welcome. Thx for watching.
