Cody Carson is an inventor, and he’s also one of those weird fundamentalists who believes in that load of unbiblical nonsense that is the Rapture (this is not to imply that if it were Biblical, it wouldn’t be nonsense). He has invented a device to detect when Christians magically disappear.
A Spring Clamp Switch was the type of vanishing sensor I built to demonstrate a working model of a Rapture Alarm in a demonstration given to a church congregation a few years ago. I used this type because it is easy to understand and can be built for less than $7. I purchased a medium size spring clamp and a pull chain switch from a local home center. I then drilled two holes in the handle of the clamp. I mounted the switch in one hole and mounted the pull chain in the other hole. Squeezing the clamp once cocked the switch. Releasing the handles cause the chain to be pulled, thus activating the switch. I then hooked the switch up to a light and placed the clamp onto a broom handle. When I snatched the broom handle out of the clamp, the light came on. When mounted to an arm or leg of a deceased Christian, the sensor would activate when the body vanishes, thus detecting the rapture.
In my demonstration, I clamped the sensor to a cow’s leg bone to represent a bone surgically removed from a Christian organ donor. This was to demonstrate that rapture related devises could be constructed in controlled lab settings and would not require the use of a grave or tomb. That sensor was wired to a computer tower and when the bone was removed from the clamp, the congregation heard an audible alarm.
