Revenge of the ants

Bill, did you fry ants with a magnifying glass when you were a kid?  Huh?




Bill Pintas was vacationing in Las Vegas when he decided to stay at the swank new Vdara hotel, a curvy 57-story tower owned by MGM Resorts.  He was sitting at the pool when he encountered something alarming.  He recalls, "I'm sitting there in the chair and all of the sudden my hair and the top of my head are burning.  I'm rubbing my head and it felt like a chemical burn. I couldn't imagine what it could be." 

Like an ant under a magnifying glass, he remembers running to an umbrella, but being unable to escape the hot light.  He recalls, "I used to live in Miami and I've sat in the sun in Las Vegas 100 times. I know what a hot sun feels like and this was not it.  My first inclination was thinking: Jesus we've destroyed the ozone layer because I am burning." 

Speaking with employees, he was alarmed to find out that the hotel staff was aware of the situation.  He recalls, "They're kind of giggling and say: 'Yeah, we know. We call it the death ray."

The "death ray" appears to be created by the glass surface of the hotel itself -- acting as a concentrating parabolic dish -- similar to those used to heat water to a boil in solar power systems.  The dish concentrates light on a 10-foot by 15-foot hot zone moving across the pool.  Temperatures in this area spike 20 degrees Fahrenheit -- or more. 


I wonder if you could cook an egg should you discover the focus point?

  1. I've stayed there but I never went out to the pool, but yes, that makes sense.
