The penguin is the only bird that walks upright.
Flamingos can only eat with their heads upside down, and pigeons are the only birds that can drink water without having to raise their heads to swallow. The most poisonous spider isn't the Black Widow - it's the Wingless Daddylonglegs, but it's fangs can't pierce human skin so it poses no threat. Oh yeah, try this one - apparently no piece of paper can be folded in half more than seven times! |
Last one is true they tried it on Brainiacs with a huge piece of paper.

but ALL supersonic aircraft have a system to 'ramp' air going into the intakes to ensure the air is not going supersonic into the engine. :wink: so, yeah.... your comment was quite correct!!! But... it could be changed to "a jet engine will only work if the air entering is subsonic." anybody know why supersonic intakes are made square? |
A 2p piece weighs the same as two 1p pieces - now that is a staggering fact!! :lol:
|
A container filled with small ball bearings has the same amount of air around them as the same container filled with larger ball bearings of the same total mass.
I remember reading that somewhere and i'm pretty sure it applies to 1 pence and 2 pence pieces too! :lol: |
