Jet engines combine oxygen from the surrounding air with on-board fuel to burn at very high temperatures and create thrust in the direction of the flame. Rockets, which we will learn about in a later post, are similar but carry oxygen internally and can therefore function in space!
In my early life I was deeply impacted by the work of physician and psychoanalyst John C. Lilly. I still have my dog-eared copies of The Mind of the Dolphin (1967) and Programming and Metaprogramming in the Human Biocomputer (1968). Lilly's work, with dolphins and the development of the sensory deprivation tank, has formed the basis of movies, music and television productions.
*WARNING* This experiment uses heat and boiling water, so be sure to have an adult around to help. This classic experiment is a fun way to learn about air pressure. We don't usually think much about the air around us, even though it plays such a vital role in our lives. it gives us oxygen to breath, carries away excess heat from out bodies, and squeezes us with over 30,000 pounds of pressure. Wait a minute! What was that last part?For this experiment, you will need:
Here at WonderHowTo, we love science. And of course, explosions. So, naturally we find Gray Matter's demonstration of fiery hydrogen bubbles pretty awesome. But the most interesting part is the reason behind the demonstration. Did you know the same gas that heats your house can also make it explode? Gray Matter explains why:
Impossible, right? Ahh, well science says fire and ice can and do coexist.
Warnings Vapors released by heater contain hydrogen,a flammable gas do not epose to open flame,vapors displace oxygen when using multiple heaters,ensure proper ventilation such as open door or top hatch.MRE and heater will get very hot can cause burns discard heater after use Do not drink water or use in food item's.

Fire. It’s everywhere— always has been. From the Ordovician Period where the first fossil record of fire appears to the present day everyday uses of the Holocene. Today, we abundantly create flames (intentionally or unintentionally) in power plants, extractive metallurgy, incendiary bombs, combustion engines, controlled burns, wildfires, fireplaces, campfires, grills, candles, gas stoves and ovens, matches, cigarettes, and the list goes on... Yet with our societies' prodigal use of fire, t...

Aside from food, oxygen, sunlight and water, there are other necessities that humans arguably need today to survive—clothing, love and shelter among them. Almost everyone wears clothes, needs somebody (or something) to love and a place to call home. And what's the one thing that connects all three? Something we all have? Keys.
Eating fire is a guaranteed method of not only impressing an entire room, but also instantly settling any questions as to whether or not you're a complete and total stone cold BAD ASS. When you can casually whip this trick out in a bar, you're not only going to get your drinks bought for you for the rest of the night, but at least three phone numbers scrawled on the backs of napkins.
