401(k) is managed by the employer and you can only pick from the funds they have selected. That really doesn't leave much choice for most people.

That's why people should consider doing a rollover into IRA anytime they have a job change and not just rollover into the new employer's 401(k).

    Marble has a density of 0.098 lbs/in^3^. So a 500lb sphere has a volume of 500lb/.098lb/in^3^= 5102 in^3^. That gives a radius of (5102 in^3^ * (3/(4pi)))^(1/3)^= 10.68 in.

    Let's say the bowl it sits in has 2/3 the radius. So 7.12in. That makes the enclosed surface area pi*( 7.12in) ^2^= 160in^2^. So 500lbs/160in^2^ = 3.14 psi. How fast do you think the water will spray out at 3.14 psi? Without any drag, out of an ideal nozzle, it would be 6.5mph. However, the pressure will actually be higher in the middle and tapers off to 0 at the edge thanks to the flow diverging and drag. So really the pressure drop at the opening is even smaller.

    There's a lot of lifting area which means you don't actually need much pressure. You can lift entire buildings with large water bags.

    If you know anyone with a sensitive nose, ask them if the place you live in smells musty or moldy. I've had family members go through similar issues also without any help from the medical system and mold was a major contributing factor. You and anyone else who lives with you will be nose blind to it and won't be able smell it without spending a week or so elsewhere.
