An apt day to remember that Dolly Parton once recorded a cover of Stairway to Heaven - and, in defiance of every moral law in the universe, she absolutely owned it.

This is a couple of years old now, but it's still a firm Christmas favourite.
One paper plate, no left-overs, one Rudolph. 😮
You can find this on the website and my Youtube too.

FAQ: “How do you make a ball out of paper?”
“I didn’t know you could make a ball out of paper!”
I didn’t anticipate this FAQ regarding a ball made out of scraps during this multi-step foosball design challenge. Background experience varies!

The bomb cyclone is a perfect example of the Fibonacci sequence in nature.
The golden ratio, aka the divine proportion, is a mathematical constant that is seen in nearly everything from the human body to paintings and art.

✨NEW✨ #STEM Tool:
A hole puncher
It’s a novel way of building the fine motor skills needed for handwriting & cutting with scissors. Hand-eye coordination is tested! ⭕️
Students punched 8 holes, & most chose to continue practicing with the scraps!

the air inside a vortex is moving faster than the outside air, the inward pressure holds the shape,

Interacting vortices
The centre of smoke rings move the fastest and have the lowest pressure, (Bernoulli’s principle)
Because of the speed the centre is travelling, the sides curl back on themselves and are drawn into the centre from the back 1/2

The same mathematical model that explains how crystals grow on a molecular level, can also explain how a species of stingless bees build honeycombs in spiraling, multi-terraced shapes
Two different spheres of science with an algorithm in common.
These hives are built by bees of the genus Tetragonula, tall nests that spiral clockwise . Each bee consistently follows the same rules in various sections of the hive and a coherent pattern emerges

there's a kid annoying his exhausted mother in the row next to me on a small plane right now so I asked him, "Have you ever thought about how weird it is that sounds existed for billions of years before ears evolved to hear them?" and now he's looking quietly out the window.
