You are watching: How to make a raft out of plastic bottles

rRaft is short for recycled raft. Inspired by Reishee Sowa, who lives on a water bottle island in mexico, this is my effort at a similar feat. If many civilization have duct tape-recorded a pair hundred bottles with each other in the past and called it a raft, mine is sturdier, has actually a genuine deck, and also is unlimited reusable.The entire process of occurring Project rRaft was recorded at rRaft.blogspot.com.WARNING: basic safety rules, as well as some state laws, dictate the you should have at the very least one PFD because that each passenger of a boat. In the pictures, we are not attract any, but likewise realize us did no row an extremely far turn off shore. Walk boating in ~ your very own risk. Also, be careful with any type of tools and also such the you use.

for ease, ns will break-up this step in to two sections. The an initial will describe the math/science that got in picking a bottle goal, and also the second will easily tell you just how to figure out how many bottles come collect.Section 1I want my raft to support myself, and also a girlfriend if the chance arises. I weight 170 lbs, and also i"m factoring because that a friend who weighs the same. That"s 340 pounds. Include in the load of the boat plus extra buoyancy to keep us over water, and we"re at 400-500 pounds of needed buoyancy.The average water bottle includes .5 Liters that water.Archimedes" principle, or the law of upthrust says: "A human body immersed in a fluid is buoyed increase by a force equal to the load of the displaced fluid."Thanks to scientific measurements, one liter of water support one kilogram the weight.If each water bottles supports half a kilogram, which is about one pound, than you need just as countless bottles as pounds you great to support. Ns used specifically 450 bottles in my raft.Section 2First, decide how plenty of pounds that cargo your raft have to support, that number is approximately how countless .5 L party you will need.Easy as that!
The most important part of getting enough bottles for her raft is to tell human being that you"re doing it. When you convince them to conserve all their bottles, collecting is a breeze. Here are a few suggestions for collecting bottles:Carry a bag through you all over for collecting bottles - i would obtain 20-25 party a job this wayDumpster dive top top recycling dayIf you or friends play sports, put a collection box where you practicePut a arsenal box in teacher work-rooms (if you"re in school) or break-rooms (if you have a job)Get girlfriend to collection at your houses, too -- One girlfriend of mine carried me a garbage bag full every mainly or so

Bottles aren"t rather fit for cruising as quickly as you obtain them: us don"t want the brand peeling off in the water and also polluting them, nor execute we desire the bit of water still in the bottles weighting us down. Time to settle down for a bagging day! First, every the bottles are dumped ~ above the floor, and I sit down and cut off each and every label. This needs to be done so the they don"t come turn off in the water...pollution is bad. Once the brand is off, every bottle"s components is cleared into a Gatorade party (One is picked out from the pile) due to the fact that most water party still have actually a little bit of water left in them, and every bit of buoyancy counts! Gatorade is the bottle of selection because lock have huge mouths, do them easy targets (and spill resistant) follow me with greater volume capacities than most water bottles. Party from juice, soda, or sports drinks need to be rinsed out, so they are separated together they go through initial processing.After the entire cache of labeled bottles is exhausted, the non-water bottles room taken to the bathroom and washed out. If any water bottles were partially full, the water is used prior to sink water. The bottles room then taken back to it is in assimilated into the general bottle population.Now it"s time for the counting! Kitchen rubbish bags room retrieved, and 50 bottles room deposited right into each one. Complete bags space thrown right into the vacant tree house out back, and the surplus bottles (Add TipAsk QuestionCommentDownload
