After taking the basic measurements of rubber ducks, the hard-hitting investigative reporters at RubaDuck asked a very basic question: If I was lost at sea, would my rubber duck be floaty enough to support my iPod? Not being ones to ignore important pseudo-socio-scientific questions such as these, we decided to tackle the engineering required. Calculations and force diagrams were penned onto a local coffee house napkin. The coffee-stained results yielded the following diagram: "floatyness" = "floaty" force - weight * - If you object to the use of the term "floaty" and think we should have used a term more like "buoyant", please contact Roger and tell him about it in 1,000 words or more. Here are the numbers for our willing volunteers: ## Tabulated Buoyancy Calculations (The Hard Data)
Data taken November 11, 2005 by DevilDucky with Ducklips as official data recorder ## Buoyancy Statistics
Standard RubaDuck statistics disclaimer: "We realize that running statistics on rubber ducks is probably some sort of blasphemy but we take our chances and forge ahead anyhow." ## ConclusionsAfter much work and pencil scratching we have found that, if fully immersed, the average rubber duck will be pushed upward with approximately 0.08 lb of force. This is not a large amount of force. For comparison, this is about 7 U.S. quarters, about 36 paper clips, or (to really put in perspective) one iPod nano. So what does this mean to you? This means that if you weigh 160 lbs, it would take about two thousand of your rubber duckie friends to keep you high and dry if your boat sank. We're not going to attempt to figure out how you would harness two thousand rubber ducks together to do this, but you get the picture. Oh, and if it was you and your iPod, it would take 2,001. |
