This blog is here to amuse you. There are funny stories, pictures, jokes and news. The content is updated every day. Anyone with a sense of humor should get at least one laugh a day. I try to find the unusual... after all you get the usual from all the other places!
I stick my hand (momentarily) directly into liquid nitrogen but don't suffer any injuries due to the Leidenfrost effect.
Leidenfrost effect is the formation of a gas barrier between a hot
surface and a boiling liquid if the temperature difference is great
enough. This gas barrier greatly slows the heat transfer between the
two and allows the liquid to last longer and consequently the hot
surface to remain hot longer. This effect can be seen in a frying pan
as it's being heated. At first the water quickly boils as it's dropped
in but at a hot enough temperature the Leidenfrost effect takes over
and makes the water skate around the surface lasting a very long time.
nitrogen vs. a room temperature object will also exhibit the effect
preventing it from instantly freezing the object... such as my hand.
The penguin in front farts and the one behind turns around
desperately so he doesn't swim into the fart bubbles. They might be
animals but they still know the there is nothing worst them someone
else's fart bubbles.
