MBPscreen moves w/heartbeat when on lap!

[flyfish29]

I'm sitting here on the couch with my MacBook Pro on my lap.

I have a window behind me which is reflecting on my glossy screen.

I notice the reflection is bouncing ever so slightly.

I thought it might be the hard drive spinning, or something else. However, no such movement when on the ottoman.

So I think the laptop is bouncing ever so slightly due to my heartbeat- or in other words with my blood pumping through my legs. I don't notice the slight movement when I look at an image on the screen, but when there is a reflection- its there!

Can anyone else recreate this?

I'm not using a MBP, but I've observed this plenty of times on myself.

Then again, I have high blood pressure, so take that with a grain of salt. (see what I did thar?)

Basic Physics, Newton's 3rd law to be exact. Look it up and all will become clear.
