Why do some biros' ink burst?

Question

is it because of the heat, or is there some other reason?!?

anyone knows what i can do to prevent it?

thanks all!

Answer 1

Because the pressure acting on it from all sides are not balanced.(just like when u write on a wall,the ink moves backward an stops writing.So try turning ur biro edge downwards when u keep it so all the ink don't move to only a place an burst it.Keep in a not too warm area to prevent the biro from expanding.

Answer 2

I never saw a ball-point pen "burst" in 30 years! You must have some really junky pens.

Buy better pens.

Answer 3

Poor manufacturing standards.

Buy "Bic" for quality.

Or use a pencil.
