Airplane follow-up
The airplane cabin is
pressurized. Why do our ears still pop? I got lots of help with this
one, thank you all. As I can best summarize, it’s because the cabin is
not necessarily pressurized to the altitude we took off from or landed
at. We might take off from here at sea level and land at Denver, a mile
high. In the meantime, the cabin pressure might be set for 6,000 or 8,000
feet during flight. We go through several altitude equivalents during a
single flight. That’s plenty of differential to get the ears to popping!

Fun fact
Baby
Komodo Dragon Lizards are known to smear themselves with feces so their own
parents will avoid them, and not eat them.

New favorite T-Shirt
It
read:
“That sounds like a
terrible idea!”
“What time?”
This,
worn in a restaurant by a guy with one arm wrapped in a bandage and he could
hardly walk!

Who knew!
Who
knew there was such a thing as Barking Treefrogs! They’re in the
Southeastern U.S., but not normally in Texas. But they are
at Lost Maples State Natural Area.

During
breeding season, they make a call like a barking dog. I found a You Tube
of what they sound like:

They
are really loud, and they can sound off, off and on, all night long.
Their call is particularly noticeable to people sleeping (somewhat) in a tent.
