How strong are silly bands?

to be honest with everyone that's on wikianswer.com i love silly bandz so much and i have a whole collection of them but the sad thing is silly bandz are not that strong so make sure u don't strecth silly bandz too much because it might fall apart and when you play with silly bandz too much it can break easily and if your wondering you can find silly bandz at walmart, paayless, buget saver really anywhere
