Should I even attempt this? (smoking at home)

[D1me]

Ok, so let's say....I make a bong out of a watterbottle or a waterfall or something.

My parents will be leaving at....11am. They will not be back until 6-7pm. This means I have 7-8 hours to myself at home.

Now, with that being said, would it be possible to smoke a bowl or two in my garage then spray it with fabreeze, and not make it smell?

In other words would the smell be gone by the time they come back?

ALWAYS SMOKE OUTSIDE!! whenever possible, thne you don't have to worry about smells. but id smoke in the garage i used to smoke in my room but my mom smelled it
