Put a hole in a bucket, it gets lighter.
Though I like to think helium, it doesn't have an odor, does it?
helium has a odor, also puting helium in a bucket would not make the bucket lighter.. : P (weighing a buacket filled with helium (obviously upside down so it can contain the helium..) would make it seem lighter when weighing it, but the truth is it is not the bucket that is lighter, it's the content in the bucket that is lighter.

also as someone pointed out: helium is not weightless, it is just lighter than air. : p
