The Black Hole is an elevated whirlpool built by Michael Yates. Visitors at Maker Faire Bay Area 2011 climbed up the stairs to witness the balance of gravity and centripetal force as they stared down into the vortex.

    Fill a 2 liter bottle 90% full of water. Cover the mouth with your hand and invert the bottle. Move the bottle quickly in a tight circle to get the water swirling in the bottle. Move your hand. You’ll get the exact same effect.

    Yup, yup, and yup.
    Serious bloggers are still around and the others hopefully are going to
    reconsider all their time spent on social media. The landscape is changing
    again and it’s a matter of priorities.

    Wow. I’ve had the same experience with Whirlpool. They are a joke.
    They’ve delivered two bad refrigerators, the first had a bad circuit
    board, the second had a leak. The “customer experience center” has
    interminable wait times and often hangs up on the customer before you
    get a live person on the other end. No one from Whirlpool can help, nor
    do they seem interested in helping. Whatever line they’ve fed you about
    customer care is total crap. Try getting through to their customer care
    center and then write a follow up.

    I agree. I have bought whirlpool products and they suck. Rather buy AEG.
    I bought my AEG washing machine 10 years ago and it is still working
    like it is brand new. Not one problem. 3 years ago I bought another for
    my cabin. Also no problem.!!!

    I hope The Simpsons show goes on for decades and decades, and is just a
    TV staple that never goes away. It works on so many levels. I agree
    with Matt though, I miss the element of the show of The Simpsons
    struggling with money and being poor. The show has gotten silly and
    relies on gags and things too much, but that’s just how the show moves
    with the times. If they keep making this show, 10 years from now, it
    will be different.!
