Clogged drain? Plunging doesn't help? This thing is amazing. I used it a few days ago.
This silly-looking thing has compressed air cartridges. You load an air cartridge and push down the handle - it blows all the goo straight down the drainpipe. Worked like a charm on my BFF's clogged bathroom drain last weekend. No mess. No chemicals. SO cool. For 30 bucks (and a very tense moment while we pushed the plunger and waited for the sink to explode), it was totally worth it.
