Deluxebase Ballooniacs - Sheep Air Filled Animal Balloon from A colourful and re-useable inflatable birthday party decoration for kids

Product Information

On the left hand side of the sheep simulation above, you can watch the sheep shuffling between the farms at random. There doesn’t seem to be any pattern to their motion. About a month later, on Nov. 21, Pilâtre de Rozier and theMarquis d'Arlandes, a French military officer, made the first free ascent in a hot air balloon. The pair flew from the center of Paris to the suburbs, about 5.5 miles (9 km), in 25 minutes. Benjamin Franklinwrote in his journal about witnessing the balloon take off:

It is also important to choose a product that still allows for a degree of ventilation. This will prevent any damp issues from occurring. Some, such as The Chimney Balloon, feature small vents, while natural products made from wool are breathable by their very nature.Now, let’s assume the sheep are equally likely to be in any of these 462 arrangements. (Since they move randomly, there's no reason to prefer one arrangement over another.) In that case, we're most likely to find the sheep evenly distributed between the two farms, because this state has the most arrangements (it's the biggest bar in the graph).

Just as when draught proofing a front door or your windows, there are many different products on the market designed to prevent heat loss from the chimney. There’s something curious here. Although the equal energy state is the most likely, it’s still very possible to find all the energy in one solid (the left or right extremes of the graph). In fact, there's about a 1 in 8 chance of this happening. So the entropy in this system can fluctuate, sometimes going up, other times going down.Today, balloons are routinely used in scientific investigations of the upper atmosphere. On occasion, specially designed high-altitude balloons have also carried people into the stratosphere; some individuals have performed parachute jumps in the extremely thin air. Balloons have been considered for space missions to Saturn, Venus and Mars, but so far, Earth is the only planet to have hosted these kinds of expeditions. Joseph-MichelandJacques-Étienne Montgolfier, prosperous paper manufacturers (a high-tech industry at the time), experimented with lighter-than-air devices after observing that heated air directed into a paper or fabric bag made the bag rise. After several successful tests, the brothers decided to publicly demonstrate their invention.
