Alum? Alum crystal? I've never heard these words. A look into lexicon shows, it's sort of a metal-salt. It can be used in multiple ways even as a lotion for eyes. So it can't be dangerous as long as one doesn't consume it. This is an interesting film the presentation of which I liked. Besides the man looks good, has an agreeable voice and fine hands. Thanks for uploading.
@@konajinx more hands on experience. With some kids actually doing the hands-on sticks with you better in life so if you ever have to use it you remember it better than just memorizing it out of a book
The near 24 minutes of this film has completely enriched my life! Brilliant, thank you for posting 🙏👍
Courses like this were much more interesting to learn back in those days compared to today where it's all about technology now.
I’m really interested in trying these experiments. Does anyone have the Film Notes - Professor Alan Holden mentioned.
Brilliant lecture.
Self-organizing matter. FYI: It's all alive
Great video!

Kids would be more attentive if school was like this today
Why?
