There is more than a foot of cushioning under the pool. Looks like about an 8″ foam pad on top of an 8″ airbag, for a *total* of more than 2 feet.

If you can produce a video of him doing it on to concrete, no prob. Until then, I saw got a video proving there was a second shooter on the Grassy Knoll, but I can’t find it right now… :)

]]> Comment on Grades: curve or no curve by larry lurio http://scienceblogs.com/dotphysics/2009/01/27/grades-curve-or-no-curve/#comment-3316 larry lurio Sun, 15 Apr 2012 22:18:44 +0000 http://scienceblogs.com/dotphysics/2009/01/27/grades-curve-or-no-curve/#comment-3316 i dont really understand how you ca NOT grade on a curve. what is the alternative? do you just decide that 90% is an a and 80% a b etc. why? that seems totally arbitrary.

The sides are vertical and 14-15 feet high. Clever commercial but very fake. As a marketing ploy the results are in the math. Google the commercial and you will find it being discussed everywhere. I even found a Hyundai forum dedicated to it. Fake or not it did it’s job……

]]> Comment on Pressure demo: suction by Iram Imran http://scienceblogs.com/dotphysics/2010/03/24/pressure-demo-suction/#comment-3314 Iram Imran Sun, 25 Mar 2012 22:34:41 +0000 http://scienceblogs.com/dotphysics/2010/03/24/pressure-demo-suction/#comment-3314 I have a GPS suction cup that I placed on my kitchen counter top without the GPS. It is not being used. I just place the suction part on the counter for a day intending to pack it away. Every few hours the suction cup falls to the floor by itself. How does it fall from the counter top where it is just resting with the suction part either facing up or to its side. Thanks

]]> Comment on When is the Sun directly overhead? by J. Snabb http://scienceblogs.com/dotphysics/2009/01/22/when-is-the-sun-directly-overhead/#comment-3313 J. Snabb Fri, 23 Mar 2012 07:53:15 +0000 http://scienceblogs.com/dotphysics/2009/01/22/when-is-the-sun-directly-overhead/#comment-3313 I was disappointed for such a US centric and non-scientific answer. I am trying to figure out the two days of the year when the sun is above 10°N where I live but this article is completely useless for that.

Make another website about Friction would totally look at it.
