Here's anothersite for you to check out next time you get
one of these "warnings" via e-mail. I have several hooks
in my lip - now I check Urban Legends :-)

Actually, I have a glass mug, that I can fill with water and nuke on high
for 3 min. take it out and drop in a tea bag and boom... it will boil
rapidly for some seconds. All it takes is a reasonably clean smooth
surface and not too much agitation.

Hi Cindy,

Now, I've never seen any UFOs but about 5 years ago I witnessed the
phenomena you debunked.
I don't recall if the cup was new but it was washed by hand and not
dishwasher squeaky clean.

My mother grabbed for the cup of water (might have been a measuring cup) =
out
of the microwave and with the first movement the contents exploded.
Fortunately she was not burned. I am glad to report I haven't seen that
happen again.

fleck of dust can trigger it into vigorous boiling. I tried this and it d=

bubbling and frothing for a couple of seconds but did not jump out of the
glass as
mentioned in the warning. We have had mail from people with first hand
experience
with this effect and they all indicated that the water exploded out of th=
e
glass.
To do this, the water temperature must be well over the boiling point."
