@builtnotbought92: ​We built a pocket-sized spot welder and emergency fire starter using two AA batteries, two metal screws, and a piece of copper wire. ​We did it by connecting the batteries in parallel so touching the screw tips creates an electric arc powerful enough to weld metal blades or ignite a cotton pad. #DIY #Tips #lifehacks #idea

WINDSTORM :

dude you applied the screws to the POSITIVE terminal

un_peu2gentillesse :

fake or fake?

ِ :

i don't want this lighting in my pocket cuh

Paul Newell :

Fake hot glue would insulate the contacts breaking the circuit

D4mi.iss_🇵🇱𝕵 :

Can I use this?

Freddie Alcala :

the hot glue can turn into insulation, hence unreliable connection... 😅

يوسف 𖣂 :

Wow never knew currents travel through glue

𝙻𝙰𝚁𝙿𝙴𝚁˖ ݁⋆.˚𝄞ᥫ᭡ :

i think it would explode

Bob :

hot glue is an insulator if used as shown

Sypher :

Totally fake. No where near enough current in two AA batteries to do that. You would need a ton of them, and the risk for one exploding is very high.

Bouangen Inthamixay :

ຈີງ

Biz Jingles PH :

huh

brent Zohan :
