Mythbusters Script Introduction: Meet our mythbusters: · Conrad Chow: WHATTSSSS UP ·  Qingda Hu: Im tired… · Jeremy Dabor: *spin around in chair On this … episode of mythbusters, Jeremy, Qing and Conrad … to test a classic physics conundrum, will the effect of a taser be increased or reduced when discharged in water. *Blue background drawing This team of 3 experts have more than 12 minutes of special effects experience between them. Do not try any of the experiments you are about to see at home! Whats that you’ve got there? Well instead of using an actual taser we decided to use a Whimshurst machine which should give us the same amount of volts, about 80,000 to be exact, as a taser. So that’s what you will be using as your source of energy? I think that elecritcity is generally amplified in water, think about what happens when you’ve heard about people putting a blowdryer in the bathtub. Right but it also might be true that the resistance caused by the water may cause the effect of the taser to pass right through the water with a reduced effect on the lucky person. Im gonna go out on a limb here and say we need a “test subject”, some water and our Whimshust machine and start testing. *Cross dissolve Jeremy holding the Wimshurst machine (normal to nerd) Science: Warning scientific content: Jeremy (nerd): Most water (dihydrogen monoxide) that we deal with today is not in its pure form. When in its pure form, the polar molecule is an insulator. However, we will dealing with an electrolytic solution, thus water will act as a conductor. Conrad (gansta): So like you put some stuff up in the wata to make sure the electricity goes through? Jeremy (nerd): precisely g-unit Qing (monotone): We can mix in some table salt and the water will become a conductor opposed to an insulator. Conrad (gasta): GET SOME…SALT. Qing(monotone): In a series circuit we will attach the Wimshurst machine… Conrad (gasta): the whimb astrust machine? Jeremy (nerd): Nice try. A Whimshurst Machine uses an insulated discs and their metal sectors rotate in opposite directions passing the crossed metal neutralizer bars and their brushes. An imbalance of charges is induced, amplified, and collected by two pairs of metal combs with points placed near the surfaces of each disk. These collectors are mounted on insulating supports and connected to the output terminals. The positive feedback increases the accumulating charges exponentially until the dielectric breakdown voltage of the air is reached and a spark jumps across the gap. Qing (monotone): …in other words, it makes a huge spark. We will connect it in series with the testing set up and an ammeter measuring current flow 100 times a second. Jeremy (nerd): If the current that travels through our “chicken” under normal circumstances is less than the current that travels through when it is in water, the effect of the taser would be increased. Conrad (gasta): so current is small outside water, big inside water, it means inside po po tase me inside water it hurts more? Qing (monotone): Yes, this is because of the relationship between voltage, current and resistance. Jeremy (gasta):in terms of Ohm's law current is proportional to voltage and inversely proportional to the resistance. The theoretical maximum electrical resistivity for water is approximately 182 [|kΩ]  ·m at 25 °C, but only 5Ω for an electrolytic solution containing salt. Whereas for humans the electrical resistance is anywhere between 10Ω to 6MΩ. Qing: If the resistance of the object is greater than the fluid it is in, the current will not go through the object. Let’s see how it looks: Experiment: *Explain the apparatus. Variables: · Variables – Ions present, spark gap, set up of appartus · Controls – Humidity, amount of water, mass and tempurature of chicken *One of each trail for the experiment Conclusion: So how are we gonna rap this up? Well the simple fact is…
