how much will it smell?

i am going over to my buddies house this weekend for 420 and we want to make firecrackers and brownies and i was just wondering, if i make brownies useing conola oil and just saute it how much it will smell.or i might use the butter recipe i dont know yet probly butter. his perents will be sleeping up stairs and they are 100 percent against pot. i think there were brain washed cause there older like 60-70 .but they will call the cops and make a big deal if they smell it and i want to know if cooking will be smelly enough to wake them up. or if they goto the bathroom (witch is connected to there room) if they will smell it and come down . he has a sliding glass door next too the kitchen mabey that will help with the smell?
any help would be greatly appreciated :jointsmile:

it will smell, but if you open the door your was talking about whenyour are cooking them it should be alright. just wait until his rents are in bed and u should be ok and the smell should go by the morning
