Cold fusion

In 1989, fusion at room temperature was claimed by Martin Fleischmann and Stan Pons, two Utah electrochemists. They believed they had sustained a controlled nuclear fusion reaction in a bench-top fusion percolator made up of two electrodes with heavy water which generated up to 100 per cent more energy than they put in. There were sporadic sightings of excess heat, which Fleischmann said cannot be accounted for by chemistry alone. However, the idea of cold fusion was discredited because leading scientists were unable to replicate the work and found no hallmarks of nuclear processes, especially none of the subatomic particles called neutrons. Their tantalizing promise of a limitless supply of cheap energy were invalid.«

Sibling lessons

Charlie was playing with his little brother Mickey when the little boy asked whether he could fly like Superman.

"Sure you can, Mickey," Charlie said, "Just flap your arms really *really* hard."

So Mickey climbed up on the windowsill, started flapping like mad, jumped, then smashed into the ground two stories below.

Horrified, their mother came screaming into the room and said, "What the heck happened?!?"

Charlie said, "I was just teaching Mickey not to believe everything someone tells him."
