Bathroom sink hair clogs. Cost: $3–7 Effectiveness: ⭐⭐⭐⭐⭐ (5/5 for hair) Review: A disposable plastic stick with barbs. You push it down the drain, twist, and pull up – hair comes out looking like a dead rat. Pros: Disgustingly effective, no tools required. Cons: Only reaches 12–18 inches; doesn't help with deep clogs; breaks easily if forced. Verdict: Every household should own one.
