This tutorial by KidWind provides details for making a solar boat for a class or hobby project.Build the best boat you can and race your friends! This boat is powered by solar panels or solar cells, which harness light energy from the sun to produce electricity. You can make the body of the boat with a recycled, cut-up milk or juice carton, which is easy to cut, water-proof and paintable (although mine are not painted here). Gabriel from California sent me this wonderful picture of his daughter and her science fair project about pop pop boats. Here is an interesting article that describes pulsating heat pipes (PHP) which incorporate the same principles that make pop pop boats work. Anyway I started doing some research regarding the uses of plastic bottles and was amazed to find them used in many versatile ways.
Currently, millions of Filipinos live without any kind of light source at all, but a band of resourceful MIT students have begun changing that.

Nigeria's first house built from discarded plastic bottles is proving a tourist attraction in the village of Yelwa.

Judges determine the overall winner based on each team's score in the five different events. Simplified instructions for creating a naked egg are available on the web at Janice VanCleave's site. Without its calcium carbonate shell, the naked egg is surrounded by a membrane, made rubbery as a result of soaking in vinegar, that is marginally protective.
They are otherwise packed to withstand shocks encountered during normal Postal Service handling.
They are not likely to be harmed by anticipated temperature changes while in Postal Service custody.
A naked egg that is too fragile to survive the inspection or weighing will be judged as having failed to survive.
Teams whose eggs do not survive will be ranked beneath any team whose egg was successfully unpacked, inspected, and weighed.
The score is calculated as the product of volume (cm3) and mass (g) of the delivered package. Straightforward construction plans for a toy submarine that can dive then rise to the surface were published in A. The instructions regarding this event are not released until it begins, so everyone is on equal footing.
Activity is the key word for this competition, with the goal being for each team to achieve the desired result as quickly as possible.The situation is designed to reward teamwork and common sense thinking as well as knowledge of physics. Every team will come away with smiles and good memories regardless of how well they master the particular challenge.
Answers will be judged according to how many orders of magnitude the team's answer is from the judge's solution. Nos dias de hoje o artesanato com reciclagem esta entre os artesanatos mais importante e valorizados no mundo moderno.

Pack the naked egg in the smallest container possible (smallest volume, smallest mass) to meet USPS regulations and ensure safe delivery. The size of the package must be bigger than 5 inches by 3 inches (according to US Post Office regulations) and smaller than 6 inches by 5 inches by 8 inches (such that it can fit into a standard rural-style mailbox). The naked egg will be inspected by the judges for remnants of it calcium carbonate shell and then will be placed on the tray of a scale so its mass can be measured. Naked eggs that survive the transport, inspection, and measurement processes will be compete for top rankings. If a team's egg is not completely devoid of their shell, the final ranking will be at the lowest level of either successfully or unsuccessfully transported eggs.

All contestants will ensure that their entry works through the application of physics principles and generally follows the spirit of the competition.
Each team will design and construct a mechanically powered, untethered submarine vehicle to navigate the course provided -- start by floating in a normal orientation for a submarine, descend, self-propel over and under obstacles, and ascend to the finish area. Any pieces of the craft that come off during the test,regardless of whether the separation was intentional, must be retrievable from the tank within 60 seconds of the conclusion of the that run. Vehicles that are unsafe or do not meet the specifications may be scratched from the competition. The craft will be tested in a large glass tank provided for this event by the generous folk at the Bowling Green pet and aquarium store, Fishey Business. Each run will begin with the rearmost end of the vehicle touching the starting end of the tank and end when the vehicle is on the water's surface completely within the goal area comprised of the last 12-inches at the other end of the tank. Ties will be broken in favor of the team that completes its high-point run in the least amount of time.
