about 4 to 5 weeks at the most depending on how long you did it for and how hard you did it for.
a long time!
It depends on the type of burn on this particular one I think maybe two weeks.
acid rain can burn and cause life-long scars. ---- ----
No when you do an eraser burn it basically just takes the skin off layer by layer depending on how long you rub. it should get red but then scab to a gross greenish color. it will bleed if you pick the scab
30 year leaves no scars.
Depends on the eraser
depend on treatment it can last up to one weak
Eraser is made out of rubber. If exposed under the sun, an eraser will take between 50 to 80 years to biodegrade.
A rubber is about 2.5cm. It depends on how long or short your rubber is.
i mean there are some like 3 inches long but some erasers or like 6-8
Depending on your skin type will determine how long the burn will last for. I have pretty fair skin and my burns last for about 2-3 days at most
It will last you a very long time depending on what you use it on. A light bulb will last you until it burns out. It is equal to what the ENIAC used.
Maybe 2.5 metres
