This caterpillar mimics a snake perfectly when frightened

As someone who is terrified of caterpillars and not snakes, this is confusing to me.

Man, nature is awesome . How comes a Caterpillar, through generations, developped a defense mechanic that look like specifically like a snake ?

"I am big mean snek. No boop pls"

Terrified of caterpillars as well. I once woke up in a tent and saw several large ones had gotten in, I panicked, reached for the zipper and accidentally grabbed a big one and smushed it. It still haunts me to this day

Powder or solid?

What am I even looking at?

Hydrophobic sand

Powders are solids

Just reaaaaaly small


DIY mirror

Don’t know whether to be amazed more at the video or the fact that I’ve never wondered how mirrors are created

I make mirrors with sputtering. We get cool looking violet and blue plasmas from the Al2O3 and Ag.

Goes in one end and comes out the other.


but seriously, how did he shoot flames out his butt?

My guess is that the stick itself has a tiny little Flair inside that he presses with his thumb after making a show of trying to break wind.

It's either that or this morning's pork vindaloo.

This is one weird cat walk.

Eh, still caught me at first. Hers my upvote

Resonance of Sand on a Speaker

I love how it gets more complicated as the frequency increases.

So cool it almost Hz ;)

i'm not going to pretend like I know why this is happening, but all I know is that it's really interesting

Cymatics, from Greek: κῦμα, meaning "wave", is a subset of modal vibrational phenomena. The term was coined by Hans Jenny (1904-1972), a Swiss follower of the philosophical school known as anthroposophy. Typically the surface of a plate, diaphragm or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste or liquid.[1] Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency.

The apparatus employed can be simple, such as the Chinese spouting bowl, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Other examples include the Chladni Plate[2] and the so-called cymascope.


Please tell me you’re listening to ?

Squeezable light bulb that can absorb color

It's just technology. A color sensor, a pressure sensor, and a few colored LEDs.



Yeah... and it's cool, but not black magic fuckery.

Squishy light bulb that absorbs color

That article was from four years ago.

It's on Amazon.

Hate to ruin the mystery, but since everyone is asking, here is an article I found on it. Does not look like it is for commercial sale yet.

I’m racking my brain trying to figure out how it works. Maybe as it inflates it’s Albert to snapshot the primary hue and the LED inside reflects that hue. That’s the best I’ve got.

I’d like to see it do various colors in the blue spectrum. It looks like it transitions well from one color to the next, but what about those small gradation changes?

How the hell do you even start doing something like this? Imagine how many tables to the face you get starting out.

Oh how the tables have turned.

I guess the person can practice with a mini table covering their head to prevent injuries.

Your username makes me think that your face has been flattened by a table before.

Erasing the floor tiles?


I'll never look at people's tiles the same way again after knowing that's all dirty and grime.

Depends on the colour of the grout though. You can get dark grey grout.

It can’t look dirty...

If it already looks dirty.
