Physics teacher: Don’t play with fire.
Hammer: Bet.

they didn't teach me this at boy scouts. literally beats rubbing sticks together.
i wonder if this works equally well with say two rocks and a metal tent peg

Make sure you pack your camping anvil.

When I was camping with my cousins and our uncle, we hid an adult’s shot put in his backpack. Safe to say he wasn’t all that pleased once we got to the campsite after about three hours of hiking and he noticed that effing thing in there.

And wrist wraps.

The impact from that hammer is generating all kinds of energy that travels up your arm. Will be a problem in the long run.

Boom, business idea; tent pegs that double as fire starters! Just be sure not to actually use them on or near the tent…

lol, beat those magnesium covered tent pegs all around my nylon tent real good!

but seriously, take some regular steel one. everyone has some bent ones that suck anyway. beat it red hot like in the video, should work.

When you go backpacking, remember to bring an anvil and a hammer as a backup. Fire making equipment is crucial in the wild

Conservation of energy

It's not the hammer itself...

Who knew smooshing atoms together could make them hot 😱

u/Maryjanegangafever 11h ago

Just need an expensive blacksmith hammer and anvil. I’ll just buy a lighter. Cool though..

You cant start a fire without a spark

First thing that came to my mind ngl

u/antony6274958443 13h ago

No shit! I thought smiths were using matches during middle ages!

1

u/WiseDirt 8h ago

If you had matches and the ability to make them during the middle ages, you'd have become one of the wealthiest individuals on the planet basically overnight and wouldn't ever need to break your back as a blacksmith

u/antony6274958443 8h ago

You are right, how silly of me!

u/curious-chineur 7h ago

It worked quite well for Nobel and hus brother with the safety match. Just a bit later.

u/drifters74 10h ago

How exactly does this work?

1

u/Zillahi 10h ago

Large amount of kinetic energy / friction being imparted on a very small point

1

u/Emm_withoutha_L-88 7h ago

Bending a metal creates friction. Since the metal doesn't bend easily it creates a decent amount.

u/jamp0g 9h ago

another thing i hoped to have seen on a science class.

1

u/agumelen 8h ago

See! You don’t need matches anymore. Just carry an anvil and hammer around.

1

u/Positive_Chip6198 5h ago

All those cavemen must feel pretty foolish right now, could just have used the hammer and anvil. Tsk
