Hi all,

I'd like to see a collection of science related fun facts here.
Only one rule: Your fun fact should start with the words "Did you know"
I'll start with an example [:)]


Did you know that the lighter was invented before the matches?
Roses are red,
Violets are blue.
Most poems rhyme,

Your right here is the correction!

#1 "A goldfish's attention span is three seconds." This theory was tested by Discovery Channel's MythBusters. The experiment consisted of training several goldfish to complete a maze. They concluded that a goldfish's attention span and memory retention lasts well over 3 seconds.

The recorded female:male ratio is 100:105 at birth.
 I doubt Steve mentioned that infanticide of females is in part responsible for this asymmetry.

In the elderly females outnumber males.

Q used to be on the Periodic table. It was element 104 (Unq - Unnilquadium), but was renamed Rutherfordium (in the honour of Ernest Rutherford) and is now symbolized by Rf. So depending on which periodic table you use, Q might actually appear [:)] My periodic table from the Navy has it written as Unq.

It's just hoax. British lied to the world if they can fight (war) in the dark night because of their "rabbit eyes". They told if they can made their eyes clear and brighten. Whereas, it's just a radar technology.

I think I have seen that. Is it the hornet that invade and try to kill the bees? Im' sure the programme that it was on was showing that the 'natural' bees, had learnt this defence mechanism, but the honey bees who were brought in to help with the orchards did not know how to combat the hornet and were slaughtered.
