  • In today's video we are testing the iron in handwarmers by surrounding them with 100% oxygen. Will they get really hot or get cold??

    If you’re familiar with PPO2, you can exceed a PPO2 of 1.4-1.6 bar whilst diving. On the surface you can get a maximum PPO2 of 1 bar (100% O2).

    I think there is some water in it because iron reacts with water only in the steam form. Some heat released by oxygen and iron's exothermic reaction will easily make the small amount of evenly distributed spread out with a large surface area water into steam. That is again an exothermic reaction, which produces more heat.

  • @DrWh1teCat
    @DrWh1teCat 3 года назад

    On the timelapse bottles, the speed at which they collapsed is more important than the degree to which they collapsed. If all bottles are the same volume and have the same volume of oxygen, then they theoretically collapse to the same degree since the same reduction in oxygen volume would take place. So, the three handwarmers collapsing the bottle faster shows the reaction taking place on a larger scale.

    An experiment with pure oxygen. Stated in the video pure oxygen helps combustibles burn quicker, hotter and more efficient. Use the the pure oxygen to attempt to run a a single cylinder predator engine from harbor freight, and see if there would be a difference with efficiency, and power of the engine. Which doing this I believe would be a little difficult because your using a naturally aspirated engine and installing a pressurized canister which in a way makes it forced induction.

    A few days late, but I think the timelapse results can be explained a bit differently. I think with Oxygen being the limiting reactant, the same vacuum is produced in each bottle, but the difference is with the water content. In the bottle with six hand warmers, there was six times the amount of water to vaporize and relieve the vacuum.

    Try seeing if you can boil metals in the foundry if it gets that hot (safely of course)

    I just want to say that while I know you guys record and schedule these ahead of time generally and I don't necessarily fault you because you gotta do content, all the things considered the episode does come across a little tone deaf at the moment. It is a fun and entertaining episode, just, you know.

    you should try mixing it with water and see how hot it would get and maybe put them in different vacuums

    Personal experience, don't use these while on a motorcycle, unless second degree burns are part of the goal.
