huh, mines fine for everything except the giant cups from fast food restraunts...

....i can even put those Starbucks frappucino bottles in it and be fine (i don't like coffee, and need energy at 3 am when i leave my apartment to head back to indiana, plus they sell them at literally every truck stop and convinence store in the US, and they taste gooood)

i just usually keep a lid on drinks if i can (cans excluded Bubba)
