i've had three tubes pop in one day.

one popped while i was away, but my roommates said it just exploded out of nowhere. the other popped while i was replacing the previous, so i had to go out and get another.

the third one popped also. i've rubbed the inside of my tire with my fingers and dont feel any abrasive things- and i've put a layer of electrical tape on the rim to try and counteract anything on it that could be causing the pop..

what the fuck is going on guys?
