Call it Murphy's Law. Call it payback for being up so late. Or just call it a giant pain in the you-know-what.
Your sink would clog in the middle of the night when you're out of drain cleaner and the stores are closed, and leaving it to sit means the kids will come down to it in the morning and make a giant mess.
Or you can go with the quick -- and green -- option: science class.
Remember the volcanoes you made as a kid with nothing more than baking soda and vinegar?
The chemical reaction produces carbon dioxide, and the pressure that builds up causes bubbles to push their way up out of the volcano for "lava."
Only in the case of clogged drains, it's your clog that comes out -- all the bits of hair, soap scum, and unidentifiable objects. And bonus points: You don't have to go searching for just the right food dye for that "real" lava look.
Wipe down the sink with a rag to remove the detritus, then pour a pot of hot water down the drain to push the rest of the clog out of the way.
A good tip: Try to bail out the worst of the water or let it slowly drain before you try this -- the chemical reaction can't do its job unless it's IN the drain.
This works like a charm in my bathroom sink and gave me ammunition to remind my husband NOT to shave with the drain open. I'll never buy a commercial drain cleaner again.
Have you tried this trick for your drain?
