Unclog your toilet with this simple and ingenious trick -- no plunger required - CNET
Over the course of many years, I've practiced and honed the ancient art of unclogging a clogged toilet without needing to use a plunger. Why not just buy a plunger? Simply put, I never needed to on account of this particular bit of washroom wizardry. This technique is especially handy if you ever find yourself staring down a stopped-up commode in someone else's bathroom with no plunger in sight -- a situation in which you might be understandably reluctant to call for backup.
I didn't invent this particular process for plunging without a plunger -- the same basic technique can be found all across the web on plumbing and DIY blogs, both mainstream and obscure -- but I can attest to its power and might.
