So, quicksand is a "non-Newtonian fluid". This is like those videos of people walking over tanks of cornstarch-water slurry.

The Japanese Kindergarten is featured in this TED talk:

Those of a 'certain age' refer to them as a "HiFi"

Oh yeah! A keeper, that one!

Matthias Wandel's "Woodgears.ca" site is worth visiting for his wonderful machines and other designs. He created a binary memory system using marbles and wooden toggles that is perhaps the best explanation of how binary memory works. Many of his projects are downloadable as SketchUp models, so you can build them yourself.

I'd hate to see what would happen if a person's head were placed in the sweet spot.

Clearly, humans need chins so we can put pillows into pillowcases. No other primate uses pillows.

Be careful when you use these words, after all:

Since Heaven it hath not pleased on thee
Deep erudition to bestow,
Or black Latino's gift of tongues,
No Latin let thy pages show.
Ape not philosophy or wit,
Lest one who cannot comprehend,
Make a wry face at thee and ask,
"Why offer flowers to me, my friend?"
(from Commendatory Verses to Don Quixote)

The water supply to a shower could simply be set to a mechanical device that measures the amount of water consumed (the water going through the pipe would make a turbine rotate until it reached a pre-determined stop, at which point the water would shut off).
The device would be on the other side of the shower wall, so to be reset one would need to leave the shower stall.

Air conditioning units should dump their waste heat into it all summer.

When I saw "Close Encounters of the Third Kind", I was struck by the size of the alien spaceship, but also by all of the lights on it. It made me think: what if these aliens never developed the transistor? Their technology would depend on giant electronic devices with vacuum tubes to switch circuits on and off, necessitating gigantic spacecraft and extremely efficient design. A collaboration between such people and ours, with our microcircuitry, would lead to a revolution in space travel.

The list includes "Fantastic Voyage", which has a great portrayal of Raquel Welch. She did a great job rebuffing the pilot (?) of the craft, who was trying to pick her up. She almost shot his hand off with a laser rifle.

The BBC, always reliable, has a video!

Are You Kidding Me? There is not enough money in the World to induce me to walk into a cave with SNAKES HANGING FROM THE CEILING!
No!
NO!
N O W A Y!

I kept thinking that the long cigarette ash would fall into his paint or be blown onto the painting. It was very distracting.
