No. That would be stupid!
Basically, energy is created and released through friction. Friction is the result of two surfaces rubbing against each other, and we can measure this created energy through temperature since heat is a form of energy. This is the same concept as rubbing your hands together to warm them up. In that case, by increasing the speed at which the two surfaces are rubbing up against each other, you are increasing the amount of energy, and consequently, the amount of heat created.

Walking: we could never walk without friction. We would have been slipping in one place. Rubbing hands together: We rub our hands together to keep them warm in winter. The warmth is generated by friction. Brakes: Brakes help to stop a vehicle in motion. Braking increases friction.

A box of matches or you could try rubbing two sticks together, but I don't think that would really work.
No. The action of rubbing together two Doritos chips would crumble them before sufficient friction could result in enough heat to cause combustion.
I would start by rubbing two rocks or sticks together. Of course i dont know much about it, but you could also be illegal, (i would not), and pread oil or gasoline on the ground and shoot it with a gun. You could use a lighter, or a bbq starter thingy. Hope this helps:)

Rubbing two rocks together
There are several ways to make a fire. The easiest would be using a lighter to get the fire going. A fire can also be made through friction, rubbing two sticks together until they're hot enough to form a cinder. Using steel wool and a 9 volt battery can also be used to start a fire.
Yes, Homo erectus is believed to have been the first human ancestor to control fire and use it for various purposes, such as cooking food, providing warmth, and protection from predators. Evidence of controlled fire use by Homo erectus has been found at archaeological sites dating back over one million years.

The most likely origin of cartoons is China. Because they would take sticks and glue them together and have a paper screen and have a lantern behind it. Then they would put the sticks behind them then and that is how cartoons came to be.
If you are talking about actually simply rubbing two sticks perpendicularly and not a traditional hand drill/bow drill/fire plough/fire saw method I can only say, that in over 60 years of informal primitive skills and survival study I have never heard of a documented case of anyone actually accomplishing that. It just doesn't seem to maximize the necessary speed and force to create an ember. That said, it is wood and friction, so I guess it is possible.Given that the fire starter had the correct materials he/she would still need to move that stick back and forth very fast and for a long time. I don't think 120 RPM/30 minutes would be an exaggeration and even then I'd be willing bet a few of hundred that that wouldn't produce an ember even on Yucca wood.The nearest thing to rubbing two sticks together that I have seen (only on video) is the fire saw method.I have always suspected that phrase, "rubbing two sticks together" came from European explorers, such as those on Captain Cook's expeditions, who saw primitive methods, such as the fire saw or fire plough or hand drill and referred to it as such, thus conjuring up the image of rubbing a stick horizontally against its vertical counterpart.
they got two sticks and put it in a circle of rocks then robbed them together then as they did that another person would find two more rocks and slam it against the sticks
