The Physics of Jars and Butterflys

[MrShoeBoy]

So I have a sealed jar with a butterfly inside.

1. Is the jar heavier with the butterfly sitting on the bottom or side?

OR

2. Is the jar heavier with the butterfly flying around inside the jar?

OR

3. Its always the same weight regardless if the butterfly is sitting or flying

Discuss... I was told I can ask for outside help on this homework project so do it well since I get a grade on this

Thanks!
