Prince Rupert’s Drops are small glass structures resembling tadpoles that can withstand the blows of a hammer and yet burst into powdery dust if their threadlike tails break. They have been a source of fascination and mystery since they were discovered in the 17th century.
Now an international research team has pinpointed the source of the bizarre shatter-resistant behavior behind Prince Rupert’s drops. The work was a collaboration of researchers from Purdue University, the University of Cambridge in the UK and Tallinn University of Technology in Estonia.
