"Many of my movies have strong female leads - brave, self-sufficient girls that don’t think twice about fighting for what they believe in with all their heart. They’ll need a friend, or a supporter, but never a savior. Any woman is just as capable of being a hero as any man." - Hayao Miyazaki
Effing thank you.
Also, I hated Gravity.
harmingly Renovated Home
The couple rebuilt both chimneys and added a hand-crimped aluminum roof to the 1820s home, among other extensive renovations.

These spectacular photographs reveal the amazingly tiny details of the life of snails. Using a macro approach, Ukrainian photographer Vyacheslav Mishchenko gets up close and personal to capture a variety of miniature landscapes as the little creatures go about their daily lives
Meet Anoxycalyx joubini, an Antarctic volcano sponge (it’s the one not wearing a wetsuit). It’s estimated that some slow-growing specimens may be up to 15,000 years old, making them the oldest living animals on Earth. Most live in such deep, frigid waters that they will never be seen face-to-face by human divers, whose entire known history has occurred in less than one spongy lifetime.

What makes fireworks colorful?
It all thanks to the luminescence of metals. When certain metals are heated (over a flame or in a hot explosion) their electrons jump up to a higher energy state. When those electrons fall back down, they emit specific frequencies of light - and each chemical has a unique emission spectrum.
You can see that the most prominent bands in the spectra above match the firework colors. The colors often burn brighter with the addition of an electron donor like Chlorine (Cl).
But the metals alone wouldn’t look like much. They need to be excited. Black powder (mostly nitrates like KNO3) provides oxygen for the rapid reduction of charcoal (C) to create a lot hot expanding gas - the BOOM. That, in turn, provides the energy for luminescence - the AWWWW.
Aluminium has a special role — it emits a bright white light … and makes sparks!
Happy Independence Day! Go watch some science!
