This video is testing the question of whether or not it matters to have the shiny side of aluminum foil facing up or facing down. The guy in the video came to the conclusion that there is really no difference in hoe the foil is placed it still doesn’t matter. The long debated thought is that the shiny side radiates more heat and reflects so then it is pressed against food the energy goes back and forth warming the food or insulating it.
This next video will hopefully be a couple good tips on how to avoid a hot car. The first one was helpful because you’re cooling or pushing off the molecules out causing them not to be so fast and kinetic. The second is to move the wheel out of the way of the duns direct radiating heat. And the third is the same concept, but you are covering with a koozie instead of moving it.
This was a great video on how to build a fire heat reflector campfire. A heat reflector is used to retain the radiated heat from a fire in the outdoors. This allows you to stay warm, while also using a smaller amount of wood which will make your life a bit easier. Essentially anything that will bounce the heat from the fire back to you will work. This specific reflector was on the small side since we had a pretty good camp set up with favorable weather conditions. Between the airflow from wind and draft, we had a well aired fire. Good survival tips!
You start out with a warm jar and cold jar of water with each having a different food coloring color added. Then if filled to the brim on each jar. Then a plastic card is placed on the blue jar and flipped upside down over the red, warm jar. Once the plastic is slid out the two colors begin mixing because of the molecules slowly intertwining with each other. BUT it gets interesting when your redo the experiment and the hot water jar is placed onto of the blue, cool jar, the colors don’t mix! The hot water has a different density then the cold water. It is less dense than the cold water so the water just sits on top. In the first experiment the cold water was more dense than the hot so the molecules would mix together.
