Oh, that would have worked if certain stuff would be possible:
1. Plants breathe slower than humans and they need the direct sunlight for them to breathe also.
2. The rubber band would block out the water, but it'll also make you suffocate.
3. The CO2 you build up in the bag would poison you if you don't take the bag off your head.
I feel smrt.
I'm also fully aware of that it's a trollface in the pic.
