From Reactions.

A liquid marble is an otherworldly combination of liquid and solid. Shaped like a solid marble but with many properties of a liquid, these strange objects were invented in 2001 and quickly went science-viral. George finds the original paper reporting their discovery but in his excitement misses the crucial fact that it’s been cited over 1300 times. So, while making some liquid marbles of his own, he quickly arrives at the STUPENDOUSLY ARROGANT thought that he might be able to make a new scientific discovery… completely missing the fact that more than 1000 scientists before him already have. But amazingly, he kinda does.

Want to contribute to this potential scientific discovery? Comment below with ideas for more experiments, practical applications for these iron-filings-encased liquid marbles, and/or papers that report something similar to what I did. If there’s enough interest, I’ll write this up, submit it to a journal (or seven) and do a follow-up video. And I’ll list your YouTube handle as a co-author.
