Could you use what's inside of the hand warmers to make thermite or some other kind of flammable material?

[@brianm6117]

Iron can be flammable when introduced to pure oxygen. Don't think it will make a thermite style reaction, but it would be a dangerous fire as its not one that could be put out with water.

[@Xande-bh5tm]

You can make pure iron based thermite like substances but the hand warmers aren’t pure iron so it would be interesting

[@morrigankasa570]

You should do an experiment with chemical heaters from MREs

[@drgnflms7]

Seeing as they have moisture, let's freeze dry em!

[@naazafreen8637]

grace being clumsy

[@peterking2651]

I had a friend stuff these in her dry suit (for scuba). As the PPO2 rose, so did the heat, so much so that she had to call the dive. 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).

[@Zillazom]

You should put several warmers in the vacuum chamber, seal it off, and see how much vacuum the iron can draw.

I definitely see the change in the way Grace handled herself in this episode compared to past episodes. I presume this change was due to the survey conducted a couple of days ago. At least we can see TKOR takes viewers opinions seriously.

[@heathergeorge6411]

I love the ending!

[@DrWh1teCat]

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.

[@jdragon622]

Can you try it sticking the hand warmers in a more rigid bottle or even a glass bottle? Also try pouring the liquid oxygen into a pile of iron. Great vid BTW!

[@jamesreynolds5938]

I would like to see more experiments with the hand warmers, please, love your vids, thanks!

[@icollectstories5702]

Dare ya to put the powder in a blender and press go! I imagine this greatly increases the surface area exposed to oxygen and should use up all the iron in a minute or so. There might be enough binders in the powder to prevent flames or explosions, but starting out with a very small amount might be wise.

[@AmyColyer-iy1nq]

Video idea- how effective are different types of hand warmers e.g. those ones versus the thermal reusable ones

[@brandonb9452]

@@epicdud5905 really? He looks maybe 6’, 180cm

[@aarushikishore1417]

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.

[@Kate-nq3no]

What would happen if you make a giant slime and flush it down a toilet? Could be kinda fun. Love your videos!

[@madisaur0]

I think those packets are made to allow a little oxygen in at a time so they will last longer, hence why the stuff outside the packets heat up faster but probably won't last as long... real question is does it burn ms. Callie!!!

[@ScottRyan666]

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.

[@Alexanderthegreat126]

Well since you said they are mostly iron, I would like to see how hard/easy it would be to forge it into a blade of Some kind.

[@timesfadingfast8991]

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

[@waelkoleilat3331]

I think the bottle with the 3 collapsed less cause it had more water vapor to offer, so it collapsed faster then the vapor came into play sloeing and stopping the collapse, similarly the one with just powder had less vapor than the packet one cause some probably evaporated while pouring them in the bottle or got left in the cloth bag

[@SuperGamer-zh4rt]
