Microwaves, can they kill ants?
So i had a bizarre thought just now, as I went to the kitchen and grabbed a hot pocket I went to stick in the microwave and I saw some ants in there then I thought, can ants die if I set this microwave on? It turns out those little buggers survived, how they did it I don't know!
30 Minutes Later...
I have been doing some research and I have found the reason why these little folks lived.
To understand why we must first look at How a Microwave ovens works.
They do not have an even spread on energy throughout the oven caverty, due to the nature of the standing waves produced by the magnetron - The device that produces the microwaves. The Microwaves are channeled to the Oven caverty by a microwave duct in the top of the oven and the concentration of energy comes from it and showers down in a column much the same as water from the shower head in your shower. The standing microwaves excite the molecules of water within the food causing them to vibrate rapidly and collide which produces heat. By using a revolving table your microwave oven passes your food under this invisible shower of energy, overcoming most of the Hot Spots that would be created by this columnised concentration of energy.
As for the ants
1. An an ant is able to sense where the Hot Spots of Energy are and stay where the energy is less concentrated.
2. The ant has a large surface area for its little body mass, so if it does wander into an area where the energy is greater it has time to turn for safety before frying.
