The author reviews a phone case that doubles as a stun gun, claiming to produce 7 million volts. The author disputes this claim, explaining that air breaks down under 15-30 kilovolts, making it impossible for the device to produce such a high voltage. The author demonstrates this using an ESD gun and measuring the air gap, concluding that the actual voltage is limited by the distance between the prongs.
The author also discusses the misconception that voltage is what hurts, not current. They explain that high voltage can still be deadly if it's not current-limited, and that signs warning of high voltage are accurate because the voltage doesn't drop when there's no current limit.
The author criticizes manufacturers for making false claims about the voltage of their stun guns, citing examples of devices claiming 6 million, 18 million, and 980 million volts. They also correct a statement made by a scientist, Zach Nelson, who said that it's the current that gets you, not the voltage.
Here are the key facts from the text:
1. The Yellow Jacket Stun Gun is a cell phone case that can output 7 million volts.
2. The device also functions as a power bank.
3. Amazon lists the device as having 7 million volts of stun gun protection.
4. The user manual for the Yellow Jacket Case confirms that it is a 7 million voltage stun gun.
5. Voltage is the electromotive force or the potential energy required to move an electrical charge.
6. The unit of measurement for voltage is the volt.
7. JerryRigEverything and Unbox Therapy have reviewed the Yellow Jacket Stun Gun.
8. In Canada, tasers are considered prohibited weapons.
9. In the United States, tasers are not considered firearms.
10. Air can break down under 15,000 to 30,000 volts across a one-centimeter gap, depending on humidity and pressure.
11. The voltage of a stun gun is limited by the distance between the prongs.
12. To achieve 7 million volts, the distance between the prongs would need to be roughly more than 3.5 meters.
13. Most European countries, Canada, and Mexico allow marriage between first cousins, but the US has restrictions.
14. It is legal to marry your cousin in Canada.
15. Stun guns work by creating an electric arc that can jump a short distance.
16. The arc is created when the voltage between two points is high enough to ionize the air around them.
17. When the ionized air areas around the two points touch, a huge current runs through the gap.
18. The voltage of a stun gun drops to zero immediately after the electric arc is created.
19. The concept of a stun gun is based on pain compliance, not paralysis.
20. The current flowing through the body is what causes the pain, not the voltage.
21. It is possible to build a stun gun or a similar device, but it may not be legal everywhere.
22. High voltage can be limited by current, and if the current is limited, the voltage must drop.
23. If there is high voltage across the body, there is no way to limit the current, and it can be fatal.
