Smoking in the car without it smelling to much?

[TheChameleon]

I wanna smoke in the theater parking lot so I can just blaze and watch a movie afterwards without driving there, I don't agree with driving stoned. So basically this is the situation, It's my moms car, I don't have my own yet. If I crack the windows slightly, spark my bowl and blow the smoke through a few straws I taped together out the window would the car still smell after about 2 bowls? How long would the smell last? The movie would be about 2 hours and I seriously don't want my parents to smell it afterwards.

I just washed my underwear for 2 hours and I still have a brown stripe... My Mom knew how to get them out...
