When you hit a bump right or the bump is just right why does it make you go woah and it feels like your stomach jumps up? Its really odd..And why does it do it when you are laying down?

That happens to me in the car feels like I left my stomach back in the dip that made that motion... I love that feeling!

It's soft, squishy bits inside you bouncing.

Anything moving will travel in a straight line unless acted on by a force. If you are in a vehicle going over a hump-back bridge then the force is the upward acceleration of the vehicle. The hard parts of you, such as bone, respond quicker than the squishy bits so there is a lag between your bony bits rising with the vehicle and your squishy bits following suit. As you go over the bump and start to come down the other side, your squishy bits are still trying to go up but your hard bits, and gravity, start to pull them down.

You can think of it as being like a bowl of jelly (jello in the U.S.). The jelly can move inside the bowl in the same way that your squishy bits can move a bit inside your body.

heh - Speaking of jello, I've just had a vision of J-Lo going over a hump-back bridge!  [:D] )
