A dust cloud of silicon micro-spheres that was illuminated by laser light scattering from the cloud is suspended in a plasma. The dust cloud is approximately 0.5” high and floats in a conical shape between the dust tray and an electrode as long as the plasma is maintained. Fundamental dust cloud properties and dynamics have applications from plasma processing to space plasmas.
This work by Elle Starkman and Andrew Post-Zwicker of the Priceton Plasma Physics Lab won the 2005 Princeton Art of Science competition - can't wait till the 2006 winners are chosen!
I remember when I was small there was that swinging boat ride at Canada's Wonderland amusment park and I had a simlar experience of being lifted out of my seat I held on for deer life... lol. I was shakey after that, didn't want to go on it ever again. It hardly goes as high as it did before, probibly so they didn't have to raise the passenger ride limit hight.
Love roller coasters, I think they just might be mankind's greatest invention. The only problem is the scarcity of them. It's like a huge ordeal just to get to the good parks.
I used to love rollarcoasters when I was younger, now... I'm too paranoid to get on one lol. Just looking at the photos of some of those gave me that sinking feeling in my stomach :P
When I was 10 one of those parking lot travelling midways showed up, and I got into that ride that's like a 40 foot pole with cars jutting out from the center spinning around at different elevations. It became apparent after a few seconds that I was beginning to lift out of the ride and hung on for fear life - the crossbar didn't touch my waist at all. I've been on rollercoasters since then but I'll never ride something that can be put on wheels and hauled away.
Thanks so much for the comments everyone. This was a fun one to write. It's amazing that an experience like this didn't stop me from riding coaster's when I was an adult
I remember seeing the Top Thrill Dragster at Cedar Point from the side and the thing was swinging like a couple feet side to side. Add to that the fact that they would stop it for maintenance every so often, and it made for some serious scare factor for the coaster.
the scariest roller coaster ride in six flags at new jersey is the kingda ka. even though itz 7 seconds its still scary it goes up 2 the length of almost 900ft an go all the waye down....it still gives me the chills even though im not riding i LOLZ
