I was putting up curtains for my parents this morning and a spider hanging out nearby had its web wobbled by pulling out the curtain pole, then it just oscillated violently for like 30-60 seconds.

Remarkably versatile creatures, i would probably die if i was getting shaken that quickly. But i guess it happens a lot to them because they usually live on their cobwebs, in suspension and at the mercy of wind or passing beasts.
