Thank you!

Hi! Thank you for your comment. Please make sure all the copper tapes are touching each other. Also, check which side of the battery is touching the copper tape. Are both legs of the LED touching the copper tape? If you have checked all of this and it still does not work, please contact us again. I would like to help😊

I am glad it helped. Thank you for watching!

Thank you for your question. This is an experiment that uses the difference in density of liquids. A liquid with a higher density sinks, and a liquid with a lower density floats. As you can see in this video, the density of a liquid is determined by what kind of molecules it is made of and how many of them it is made of. I hope this helps.

Yes and you can keep repeating it as well.

Congratulations! I'm so glad it helped!!

Thank you for your question. Because CO2 is a gas and lighter than water, CO2 rises to the surface of the water. As the bubbles burst, the vinegar inside the bubbles sinks. This is because vinegar is more dense than water. I hope this helps you.

I am glad it helped 😊

It lasts for about 4-5minutes

wow thank you for your lovely comment. I’m happy it helped you :)

Thank you!

Thank you😊

Siuuuuuuuu!

You have glitter and food coloring?

Yes! Try it with various materials glitter, food coloring, spangle, small beads, Lego figures and so on!

Ok

Yes, sure! Thank you for your question. When vinegar is added, it sinks down through the oil since vinegar is more dense than oil. Vinegar meets baking soda which stays at the bottom and they produce carbon dioxide(acids and bases chemical reaction). When bubbles rise to the top of water, they take some vinegar. The bubbles pop at the surface, and then vinegar droplets fall back down because vinegar is more dense than oil. And the chemical reaction continues. Hope this helps you. If you have any more questions, feel free to ask anytime :)

​@@sodapopscience2280 woah! Thanks.... And its me the one asked you the explanation from another account.. anyway thanks ...❤❤❤❤ So helpful....❤❤❤❤

​@@sodapopscience2280 A small doubt ... Can you please just clear it... 😊 Here you say when bubbles rise to the top of WATER ... Have you used any water here for the experiment...😢😢

Oh, that is a good one. Sorry, what I meant was top of the liquid :)

Sure! Do you want me to explain it again in the comments?

Thank you!

thank you 😊

if it is hard to get corn syrup around you, you can use honey or maple syrup instead of it.

Wow thank you! Good luck with your project!

Thank you for your lovely comment 😊

Thank you 😉

Thank you for your question. It works for about 4-5 minutes. If you want to close and keep it for later use, it should be closed after finishing making bubbles. However, it is recommended to empty the bottle after each experiment since this is for an instant experiment. Thank you for watching this video. Hope this helps :)

Thank you for watching ✨

It will depend on how much you put in. Mine lasted for 4-5 minutes. If you want longer, add more vinegar.
