The best material to build a 2km dam on...

has to be water-soluble gypsum (nl: gips). They did it in Iraq in 1983! The Mosul Dam:

• Mosul Dam is Middle East's fourth largest dam in reservoir capacity and Iraq's largest
• Key component in Iraq's national power grid, with four 200 megawatt (MW) turbines generating 320 MW of electricity a day
• Built on water-soluble gypsum, which causes seepage. Subsequent erosion creates cavities beneath dam that must be plugged or "grouted" on a regular basis or dam will fail, say experts
• Array of piezometers have been deployed to measure water pressure and leakage
• Seismic equipment provides information to monitor dam's stability

Here are some large scale panoramas. I like the zoom function! perhaps we should introduce a label 'panorama'?

Test Panel

I need you guys as a test panel for one of my assignments for study. It's supposed to be a pictogram -like a traffic sign- so Im looking for one or two words that pop-up in your head the second you see this...

try this,
I added a waterline in the glass to actually make them look more like wineglasses.
I added bubbles to make it look like champagne instead of normal wine.
Adding an explosion type thing is kinda hard with only white lines, but I did what I could.

edit dekus:
As a reply to wiki's last comment, I made one with the glasses in the center, though I also added people which I'm not very pleased with so thats why this design didn't make it. I have to present this assignment tomorrow so any good thoughts are still welcome!

this is a fast sketch on how it looks like when you put them togheter. by wiki

Great Pre-flight Safety Announcement

It's a bit hard to understand sometimes, but it's much more amusing than your standard safety talk.

James Randi and Project Alpha

Project Alpha was a hoax orchestrated by the stage magician and skeptic James Randi. It involved planting two fake psychics, Steve Shaw and Michael Edwards, into a paranormal research project. The researchers became convinced that the pair's psychic powers were real. The hoax was later revealed publicly.

Wikipedia has a really interesting article on this project. Gotta love Randi and how he destroyed the pseudoscientific parapsychology field.
