By Stephen Ornes / October 1, 2012

Both of these steel balls are superheated to 400 degrees Celsius (750 degrees Fahrenheit). But the one on the left has been treated with chemicals that repel water, and as a result it doesn’t produce the explosion of tiny bubbles that precede a boil, as seen on the right. Credit: Ivan Vakarelski
