I really enjoyed showing this video to my kids as part of our homeschooling lesson. One of them pointed out though, that the cup that the gel stuck to was made of plastic, not glass.
@@dr.milner-bolotin_talks3505 I checked the comments specifically to see if anyone pointed that out. Figured someone would have.... and, yep, sure enough. :)
@@DonaldKronos The point is the relative values of the indices of refraction. Depending on the kind of plastic or glass, you can match them with the indices of refraction of the sodium polyacrylate bubbles.
My grandfather invented that stuff. One time he was at our house, and cut a piece of daiper, then put it in a glass of water. After it finished absorbing, he drank the gel, and I believe the two pieces of daiper that were around the powder as well. He showed how safe it was, but I do not recommend anyone eating or drinking it. Even if the powder becomes fully saturated, I still don't recommend it, because I am still not sure how exactly the body reacts to it. My grandfather, before modern sodium Polyacrylate was widespread in daipers, he made some sodium polyacrylate with radiation, which he said two hands combined and full of the stuff could absorb several thousand gallons of water. He was upset people didn't buy it because they thought radiation was dangerous. He didn't think it was dangerous.
This is so cool. Thank you for sharing. I just have this information: en.wikipedia.org/wiki/Sodium_polyacrylate But having a grandfather like that is very exciting.
You have to good it up. We haven't tried it. Or even better maybe you can try. My guess would be that this will not work as alcohol has huge molecules unlike water and they are not going to attach to the polyacrylate the same way H20 does.

Good point. Thank you for clarifying. I am glad you found the video useful.

Very interactive and useful diagrams and pictures to support your explanation! Great job!
Hi sir I want to prepare sadium polyacrylate will you please suggest easy way to preparation method?
Sorry, I do not know how to prepare it. Maybe you can google it up and share with others.
I believe it is too complicated for you to make easily. My grandfather, who invented it, was a chemist.
Cool!
are there any solvents to dissolve this
Could you also explain: Why does table salt reverse the gel formation?
Dear Hamoun. I do not know why this happens. It would be great if you could find it out and share with us. Thank you in advance.
salt attracts water. That is why it is good to have plenty of salt in your body. Your body uses salt to direct water where it needs to go.
I believe salt has a negative charge like sodium Polyacrilate
Is it eatable ? Toxic ?
How many time it remain as snow

how he used radiation process explain a bit
Hi, I wanted to know that what happens when Sodium Polyacrylate is exposed to alcohol instead of water?
You have to good it up. We haven't tried it. Or even better maybe you can try. My guess would be that this will not work as alcohol has huge molecules unlike water and they are not going to attach to the polyacrylate the same way H20 does.

cool
dammit, I forgot my scoopula... AGAIN! 🤦♂
